PetCo Baby Betta Care

So most of us have come across the Baby Betta's at PetCo or perhaps you've just stumbled across one on your travels! You pick it up and don't see anything in those cups until you turn it and there's a tiny Betta! You marvel at the size and perhaps it breaks your heart because the poor baby is laying on its side, looking so hungry. So you decide to pay the 1.99 and bring this cute little fish home.

So you get home and suddenly wonder, do I treat this baby like a normal Betta? Do I just give him pellets and do a weekly water change? The store worker gave me what seems like good advice; maybe I should double check it! If you are wondering how to care for them, then step no further! You've found the right place!

Let me start off by saying that these are baby fish, think of them as you would a baby human or a baby kitten or puppy. When you think baby human you think a lot of work right? Lots of screaming and kicking and changing diaper's three times a day. Well don't worry; it will be easier than raising a baby human I can promise! But all the same, these are baby creatures that require special care as opposed to their adult counterparts.

So let's start with:

Water Changes
Growth Stunting Hormone: Baby Betta's excrete something called a Growth Stunting Hormone (GSH). This generally is more of an issue when other babies are divided in the same tank or growing up together in a spawn. The hormone is a signal sent out as an appetite-suppressant for younger, weaker fry which in the end stunts their growth and they don't grow as quickly or stay as healthy as the older, stronger fry. Here's one of my favorite quotes about the GSH:
"Well, we have a scary message...they grab a bite to eat but are totally stress that Bubba is going to whack them ALL THE TIME. In the wild, urine messages left by big cats are designed to stress other big cats into leaving an area. Could we have the same thing with no place to go? Although they eat some, our babies may not be able to utilize all the food they consume because they are so stressed. It would be like trying to work with someone yelling at you all the time!"

There are a few ways to combat the GSH when keeping multiple babies or even just one (sometimes they can see their reflection, think it is another fish and excrete the hormone which backfires in the closed eco-system [your tank] and can stunt the baby itself). One of the more popular ways and easiest ways to get rid of the hormone is to do daily water changes. You see breeders do this all the time, not only does it help water quality but it helps decrease the amount of hormone that is in the water.
How much is enough? The smaller the tank the more you should change, especially if it is a 1 gallon. It is not recommend keeping babies in anything smaller than 3 gallons because of the sheer simplicity of not having to do water changes as much; that helps your back doesn't it? Regardless of tank size I generally recommend doing around a 50% water change daily for multiple babies, every other day for single babies with nothing else in the tank.

There are two other ways to help reduce the hormones effect which are as follows; have a heavily and active growing planted tank and allow the Betta to grow up with other fish such as livebearers (guppies, platies, endler's). Both of these will reduce the effects generally and help aid the fish in their growth. Of course the best way is to combine all three of these methods but for the average Betta fish keeper, it's easy enough just to do the water changes! This all being said, don't go running out to buy a baby platy unless you know you can care for it the same as it gets older.

How Often Do I Feed?
Thinking about a baby human, kitten or puppy; they drink pretty often from their mother's milk, correct? The same goes for baby fish, generally they will eat every 3 to 4 hours on a high protein diet. 3 times a day is fantastic but twice a day is the normal for the babies. You want to feed them small but frequent meals through the day. Once in the morning and once at afternoon/evening time is a great schedule to get on!
Feed until the baby has a nice rounded tummy, yes their stomachs are the size of their eye but same as in humans; their stomach are meant to expand which is what you want to see.
This is a healthy expanded stomach for a baby, even a little bit more but around this is what you want to see for a single feeding and then the stomach should reduce before the next feeding:

What Do I Feed?
Let's talk a little bit about food quality and how we know what is a good food and what is a bad food. For those who keep dogs and cats, the same applies for fish food and fillers. Fillers are ingredients that do just that; they fill the food cheaply which allows the company to sell the food for cheaper but that means the quality has gone down too. Fillers are generally very indigestible for most fish which means it's easier for our fish to become constipated or backed up. Fillers consist of Corn, Soybean and most Wheat content.
Ingredients are generally listed by weight, so the closer to the top of the list; the more the food is used. However, animal foods are not required to be listed by weight however I do know the New Life International (New Life Spectrum) IS listed by weight of the food. So in most cases the top three ingredients are the more important ones to look at, you don't want to see those nasty fillers in the first two ingredients for sure, in the third ingredient is okay but not fantastic. If you see Whole Wheat in the third slot that is okay! Wheat is often used as a binder to hold the food together. So in the first ingredients you want to see things such as Whole Fish (whatever it may be, be it Halibut, Salmon, Krill).
New Life Spectrum is highly praised around here with Omega One coming in very close second. One of the main differences in the two is that NLS also contains garlic in their formulas, garlic is not only palatable (fish love the taste!) but it also helps ward of parasites as it is a natural anti-parasitic food! Omega is also great, it doesn't have garlic but its ingredient list is still pretty darn good! My only qualm is that they split up their wheat content to make it look better when their wheat content should really be around 2nd or 3rd on the list, otherwise it's a great food.
For your fry you want a high protein based food, NLS does have Grow Formula which is formulated specifically for your fry but it can be expensive, especially if you are not raising fry all the time, so instead you can get the Small Fish Formula or the Betta Formula. Main differences between those are; protein and fat content in Small Fish are higher than in Betta Formula, Small Fish is also a .5 millimeter pellet where the Betta is a 1 millimeter pellet. You would have to crush the Betta pellet but that's not so bad, you would have to do it for the Omega One as well.
If you cannot find these foods, next best in the pellet world is the Aqueon pellet; again you would have to crush it for your baby. Flake foods are generally not so great, especially in lower quality foods because they can cause issues such as constipation and swim bladder issues later in life. NLS and Omega are the only flakes I would ever use on a baby.

Frozen foods are a fantastic choice for your baby. You can get anything from bloodworms (the more blood in them the healthier they are so steer clear from freeze-dried BW's), daphnia, brine shrimp, and more! Daphnia are great natural laxative for our Betta's, they are great to use for constipated Bettas and for Double Tails who tend to be more prone to constipation and bloat. Brine Shrimp and Bloodworms are also a fantastic source of nutrition, for most adults once or twice a week is fine to feed but for babies you can feed daily/every other day if you see fit but do not over feed! Remember, small but frequent meals! Frozen thawed foods can be stored in the fridge for a few days but no more than 3-5 days otherwise they spoil! You can also chop up your frozen blocks into tiny pieces and wrap up the blocks you don't use so they don't get freezer burn, wrap them in aluminum foil and store in freezer. Never thaw and re-freeze!
Live foods can also be feed daily if you happen to have them; Grindal Worms, Micro Worms, Vinegar Eels are all pretty easy to culture if you know how. If you don't, no worries, just stick to pellets and the frozen food.

How Can I Tell the Gender of My Baby?
This one takes a good eye to really see the differences. Many believe that the Egg Spot or Ovipositer is a sure sign of a female, this is not the case. Betta's seem to only exist to throw us off our game! Many young males will frequently have fake egg spots which can be very confusing! Many will even keep them after they hit maturity! So the only real way to tell if it is a male or female is to find the ovaries! The ovaries are located behind the bundle of intestines and stomach area. If you see the egg spot, right above it is the tangle of intestines and stomach area, it should be nice and round. Behind the stomach should be a cone shaped organ on the females which is the ovaries. Each female may have different sized and shaped ovaries, some are larger than others and some will carry them high while others will carry them very low. When I say "high" I mean close to the swim bladder and then "low" is closer to the anal fin. Males will obviously not have ovaries.

Now that you know about the ovaries, there are some other small differences that can help you determine sex. Not all of these ring true all the time but I always look for the ovaries first and then confirm it with the traits that I see.
  • Females:
  • Small eyes
  • Smaller ventral's
  • More pointed shape of the body <--this one is more often not useful in sexing.
  • Shorter Fins, more distance between the dorsal and caudal
    A photo example of a female, do you see the yellow cone shaped ovaries behind the stomach?

  • Larger eyes
  • Longer fins all around with shorter distance between the dorsal and caudal.
  • A smoother topline <--again, not useful for first line of sexing as often these babies are not Show worthy specimens so therefore the breeder doesn't follow guidelines about form or sometimes these fish are culls from a spawn and so they can have deformities.
A photo example of a male, do you see there is a space behind the stomach, no ovaries.

Another note: All males and females can flare and be aggressive. Half the time my females are way more aggressive than my males so that is also NOT an indicator of sex. Both sexes have beards however males beards are larger and stick out more where female beards tend to not stick out so much.

Why Does My Baby Have Stripes?
There are a few reasons for this. Juvenile fish need to hide in the wild so they don't get eaten! Horizontal stripes or Stress Stripes are not always an indicator of stress for baby fish, especially when growing up. These fish use horizontal stripes as a camouflage system and as they increase in age, their colors come in.

Vertical stripes are also known as Breeding Stripes and Submission Stripes. In babies the "alpha" fish will display these stripes, letting everyone else know to back off and that they are the alpha fish here. They do not mean that the fish wants to breed and nor can you breed them until they are sexually mature.

Both sexes can have both sets of stripes. Bettas can also switch very quickly between these stripes and their solid colors, they are nothing more than a visual indicator for other fish and sometimes helpful for you as well! That is usually more for adult Bettas though so I won't talk more about it since this is about baby fish!

How Do I Know When My Baby is Mature?
Males are easy to spot generally; they will start to build actual bubble nests of decent size. That is the general sign of sexual maturity in males, in females they can become eggy at this time but it's difficult to really tell when they are matured other than that. Roughly 3 months of age is normal for Bettas to become sexually mature however since PetCo babies have gone through so much stress and possible trauma, they may and will take longer to grow and become mature. Some are lucky to not be so stressed and grow as they should and hit maturity right around 3-3.5 months of age.
Also a note on bubble nests, males will never build them right next to the filter unless the filter is extremely baffled. If you see bubbles forming around your filter then most likely it is from the filter. The filter also tends to produce smaller bubbles where males will produce larger bubbles for their nests.

How Long Will My Baby Live?
This is a difficult question. Because of the care they previously had it all depends on many things; how stressed out the fish was during shipping, if they were mishandled, how long they sat on the shelf, how long they went without food and more. The average life span of a PetCo Baby is around a year to a year and a half. Clearly, this is shortened to the normal two to two and a half years for the regular adults that we buy, the more stress the baby has gone through generally the shorter their life span.
We, as fish keepers, have to strive for basically one arching goal in the fish world; to keep our fish as stress-free as possible. Most of the time stressors can be avoided if you pay attention but sometimes it's unintentional and that's alright, it's a whole learning process and one day you might get lucky with a PetCo baby that lives 3 years! So it all comes down to care and sheer luck.

Please do not post pictures of your babies here, go to the Official "PetCo Baby Betta" Thread to show off your babies. You can, however, post questions here about baby care if something is not clear.

I feel like this should be a sticky, since the baby betta fad is still going strong and this is great info! :3

I am curious about where you got the one year lifespan estimate though; through personal experience or was there a survey or something?
Thanks guys, glad it finally got some attention. I'd linked it on the PetCo Baby page but it can't be a sticky since we're still trying to clean up all the stickies so just feel free to post this whenever someone has a question that I've answered here. I've got it bookmarked for fast access ^_^

@Rana, the life expectancy is from my own experience and from those on the Official PetCo Baby Thread, one year is on average but just like those who are not stunted, this can vary greatly. Some have had great luck with their babies and they live the normal 2-3 years while others have not been so lucky. My oldest living baby was 2 months over a year.

Ah, I didn't even think about referencing the thread but that makes sense. My first baby is about a year and a half and still chugging, but my other two died young (Birth defect & illness respectively).

I wonder how much has to do with the breeders they came from, whether they were runts or not, etc. If my family wouldn't kill me I'd be tempted to buy a bunch from different stores and make an informal study of it, since they'd have the same care...
I'm not sure, I would like to know what is stunting, what is born illnesses, what is birth defects and how all of this plays in with the breeders and their ages. My oldest baby at the moment was much older when he came in from the breeder and so he's doing amazing right now so to me it seemed like the breeder cared a little more for that spawn. Could just be luck but it would be interesting to really know.
Thank you for making this for others. If only you had made this before I got my baby
This is a great thread. You basically put together the several hours of research I did when I first got my baby. Wish I had found this forum and this post first!
Thanks Lily! You can share it where you want to on this forum (if it goes on a different forum I'd like to be quoted at least) to help people out with their baby-endeavors ^_^
First off, this was so helpful! I am feeling very confident after reading this in raising my baby. Could you take a look at the pics i posted in my profile and give me a sort of assessment on how old it might be and m/f if old enough and if it looks healthy enough to survive?
I did comment on the Official PetCo Baby Thread as well and showed you pics of my fish as well. Yours looks older than my boy Pierce but I can't say exactly how old your fish is, it's older than the month old fry that is normally there though. I'd say around 1.5-2 months of age roughly.

It's definitely old enough to sex but I'd need a more accurate picture, preferably one where you shine a flashlight behind the tank so it's pointing at your camera and then when the fish swims in front of the light, take a picture. This will allow me to see if there is the shape of the ovaries or not but judging by your pictures, I'm leaning towards not which means boy. And s/he looks incredibly healthy, you should be just fine!
Thank you so much! Sorry i didnt recognize that it was you that posted lol. Hard to see on my cell phone screen. It is hard to get a good picture of him because he moves so much and doesn't seem to like his picture taken. I dont use a flash and the light in the tank comes from the top so I guess for now I'll go with it being a boy unless I get a better picture to show you :)
That's fine, you don't need to use flash, just use some sort of light behind the tank so it can show through him. With all fish, you'll take many pictures but maybe only get one good one out of it lol, it's the nature of fish in general or rather anything with a lot of energy and the smaller they are, the harder they are to photograph ^_^ Try cupping him in his PetCo cup (if you didn't throw it out) or feed him to get him to stay still a little while.
Thanks for the advice. It is good to have some reassurance. Im glad i did good picking him out. I saw some other nice babies at my local petco but when i saw him i had to have him because i have been wanting a DT and couldn't pass him up. Luckily my petco has a fish expert working there and he takes really great care of all the fish. They clean out the betta cups daily and feed them. Very few that were dead. Only one or two. All their babies were alive and swimming. I just hope they find homes soon!
That's great! It's always nice to have a really good store ^_^ we have a few around here too that are really good :-D
Lil, I wonder if you can help me with this:
I noticed this morning that one of my babies (2 months and 1 week old) is swimming only at the surface and on one side. It seems like he can't stand straight. He also seeks plants to stand on. All the others with which he shared the BIG tank are fine. I've put him in a suspended plastic pet bottom, in the same tank, to give him time to rest. What can I do to help him?
I do 30% water changes every other day. Temp:27Celsius. I alternate feeding them frozen cyclops, blood worms and pellets.
Yesterday I did something extra: I added some solution for black water from Tetra. A lot less than it was prescribed on the label.
I have no idea what happened only to him and to none of the others.
Other details:
- this is the biggest of the babies (I used to call him Sumo, until his colors showed)
- at first I thought he was going to be marbled something, as he was pinkish with black dots, but now he is pink (like fish flesh) with black and transparent fins. I guess something like a butterfly, but I'm not sure if I'm correct.
- he has black eyes and also his lips are black as if wearing lipstick. He is so cute!
I'm telling you this because it might point to some genetically related disease... He's not albino or something, but still... that fleshy color seems unnatural. Nevertheless he is absolutely cute and very dear to me, as he was always the first to check the food and to welcome me every time I went to look at them.

Sounds like he's a Cellophane, that's a flesh tone with clear fins.

It sounds like he could have swim bladder problems, he could also just be too traumatized from his ship to the store. Either or, there isn't much you can do about him. You can post a picture here or a few to see if I can see any deformities on him or anything.
