Really need to refresh my betta knowledge as soon as possible - thanks for your help

Hi all,

I have very recently adopted a betta who is a known tail biter.

I have not had any fish for quite a few years now - and the only ones I've ever owned were betta's. None of my betta's ever ate their own tails though. So I have been obsessively searching the info to update my care knowledge and also read up on this self inflicted tail damage problem.

Hoping some of the very knowledgeable people here will be able to keep me on the right track with this little guy. I have learnt from other posters the importance of keeping photo logs to track progress so am doing this also.

He was originally purchased by his previous owner as a beautiful half-moon but his owner tells me that he quickly became a consistent tail biter and in the 10 months since she bought him he has routinely eaten more than half the length of his tail off. She tells me it does start to grow back but despite her best efforts he just always chomps it back down again (she had concluded that perhaps it is just too heavy for him and he likes it shorter).

I am keen to troubleshoot this problem behaviour and help this little guy to be happy and healthy if I can, hopefully breaking the tail biting habit and grow back his fins to their gorgeous natural size. But I am definitely not a betta/fish expert. I have owned numerous Betta's in the past and none of them ever bit their own tail.

I am using the Seachem Prime Water Conditioner (as was his previous owner) and I was wondering if I could also start using the Seachem Stress Coat as part of his everyday water content and if that would help the growing process for his tail? Also looking for clarity about whether this product is used WITH the prime water conditioner, or instead of, or only ever meant to be used in a treatment/hospital tank to encourage repair of visible wounds instead of as an always included product after water changes.

His previous owner assures me that although he has been a tail biter since his day one with her - that he has never suffered fin rot as a result.

I have been shown the photos of how he looked when he was younger and she had just purchased him and at that time he had zero tail damage – his tail was full and beautiful so I know the behaviour started once he made the move.

Since I agreed to adopt him - I have been researching like crazy about ways people find work with their tail biters to break the habit and repair the tail.

Poor little guy. :(

What I know of his history:
He was purchased in Asia and then transported in a suitcase.
Since then he has been living in a glass bowl that is about 3 gallons (for about 9 months now).
No filter.
No heater.
At least once or twice a week 100% water changes.
Owner’s feeding routine was giving him 4 Hikari baby pellets a day for food (usually given at four spaced out / different times of the day, so one pellet each feeding time) – on one day of the week though he was getting frozen blood worms.
He has had the 3 gallon bowl all to himself but I believe his glass tank was sitting next to another glass betta bowl in his previous home.
I have taken him in and purchased the bowl he has been living in from his previous owner.

I am just about to place an order for completely new decorations such as plants / floating log / mirror etc to just experiment and gradually swap out one by one all of the decorations he currently has and has always had in his bowl and see if perhaps one of the objects in his environment has been the tail biting trigger.

I've also read that sometimes just moving the position of the tank or the lighting in the room etc can be enough to break the cycle (depending on why the fish is doing it) and so will wait a week before changing decorations to see if he is happier just from being in his new location inside my home.

Very keen to help this little guy repair his beautiful tail because the photos of him are truly stunning before he ate his fins back to kind of delta size but also because this behaviour doesn’t seem to be an indication of a happy, stable, content little fish.

From all my research, and in trying to pin point the WHY he is doing it - he does not fit the criteria of a 'highly aggressive' or 'skittish/neurotic' fish...so I'm leaning toward he may have always been too bored, too hungry or it is a hereditary bad habit. He seems like a happy guy, doesn’t act sluggish, or scared and is always eager to come straight up to the surface to greet me for food. Spends most of the day just calmly swimming all around this bowl.

I have read about the possible solution of getting him some companion fish to see if that keeps him more occupied and less interested in his tail but as he has never ever had tank mates before I would like to try all the more subtle changes first. If it gets to this point; How many companion fish would you say is a happy and safe mix in a 3 gallon tank with just one betta? (and which companion fish would be most recommended).

So any other advice you can offer regarding successfully repairing his fins – but most importantly stopping the biting would be appreciated.

I am also interested to hear from Betta owners who swear by or swear off the Moss balls (both the Marimo live Balls and the Fluval imitations – and the pro’s and con’s of live v’s artificial in an uncycled tank).

Lastly, is anyone able to tell me if you have ever heard or seen any info regarding whether dried blood worms are known to cause constipation / digestive problems with betta’s. As compared with using the frozen blood worm cubes?

His previous owner loved him very very very very much and I’m sure she took very good care of him and all her other betta’s (he was the only tail biter she had) – She had tried many things to break his bad habit and is knowledgeable about betta’s but I still have my fingers crossed he may be able to be helped.

He has been with me a few days now and I have not actually caught him in the tail biting act – but I am preparing myself because I have been shown pictures by his previous owner of him with part of his tail still hanging out of his mouth!!! :eek:

Thank you very much for any help you can offer and also for sharing your time.

Kind regards,
Onbu.

You need a ten gallon for betta tankmates that are fish also you need a heater.
Well, it certainly sounds as if you've done your homework already. Unfortunately, I can't really add all that much to the discussion except to say that it's different with each fish. I've had several tail-biters in the past, and while I was able to somewhat curb the behavior in 2 of them, it never really went completely away. One seemed to bite if his environment was changed in any way, so I would leave the plants relatively stationary and perform water changes carefully so as to avoid stressing him out. The other was a half-moon who just seemed to dislike his long finnage as his tailbiting episodes did not correlate with anything else.

As for my third tail-biter, he was really a chronic case and would tail-bite no matter what I did. He was a rescue and had severe fin rot when I bought him, and I pretty much concluded that he didn't like the weight of his tail because his biting coincided much more with the length of his tail as it grew back than any outside stimuli or changes. He "trimmed" his tail for the duration of his life but otherwise always seemed happy and healthy.

The one issue I see with your setup is the lack of heater. Bettas really are a true tropical fish and will be happiest with a temp. around 80F. Good luck with your little guy!

Hi Kim,

Thank you so much for sharing your insight - his previous owner had literally come to the same conclusion with this little guy. She described his behaviour to me as 'being his own barber' because he always eats his tail back whenever it starts to grow back to healthy/normal size for a half moon.

I have not really read anything concrete on the subject though - as you say everyone seems to be experiementing with different solutions for every different little fish.

I am certainly not an expert and at this point I still feel this habit is so sad and he must not be happy - because I have not read anything that supports that it is 'natural or normal' for these guys to 'trim' their own tails to their desired lengths.

Have you seen anything supporting this behaviour as completely healthy in some of the betta's who just dont want a huge tail?

What is the Temp?
I have been monitoring the temp and I do see it is a problem :(

What is the Temp?
Hiya,

His previous owner told me she kept her house at a constant 24 degrees celsius.

So before I took him in I turned my climate control unit setting to 24 degrees celsius also, so as to reduce the stress induced by all the changes/moving house for him. I've been trying to keep everything as consistent as possible for him since taking him on so I could avoid a sudden shock death and also monitor his usual behaviuour.

He has been with me two nights now and despite his previous owner never doing so and feeling if the room temp stayed consistent so will his water - I have inserted a digital thermometer into his tank so I can monitor what I assume will happen even with the climate control set, thus being unavoidable changes throughout the day just based on night v's day time etc and sunlight/warmth/heat through the rooms windows at different levels throughout the day.

I realised today his water was still reporting too cool for him though - so I have pushed my room climate control aircon up to 26 degrees. Am hoping once the room warms up this will have a positive effect on his water temp rising.

I would still reccomend a heater they are really helpful. What is the tank size and are there lots of hiding spots sorry if I did not see it and its in there.
Thanks so much for trying to help me

Hiya,

He has been in a 3 gallon tank.
By himself.
I've kept him in the exact same tank at my place.
He has a little house down the bottom that I am told he has always had and he likes to pop in and out of there, especially likes to sleep in there.
There is a little penny wort plant on top of the house.
And there is a fake floating lily that I have been told he likes to make bubble nests under.

I can see that at present there is not enough hiding, playing or resting space scattered inside the main space of the tank though as the shape of the tank means the base is quite small and fits only the sleeping house and the penny wort that sits on top of the house is too small to provide 'near surface' resting spots or for him to play/hide between foliage etc.

So I have today placed an online order for a few new things to switch around and experiment with which will hopefully arrive in about two weeks:
Exercise floating mirror
Mini floating betta log with feeding hole
Different types of floating lily options
Variety of different types and sizes of silk plants to try out
Seachem stress guard

And I am going to keep an eye out for a different little sleeping house to sit on the bottom where his current one is that he really likes, just in case something about the shape or colour of the current one is upsetting to him.

Sounds good you have a lucky little Betta quick fact the Betta avergaes 2-3 years in bowl and averages 5-7 and rarely ten in goos envirements cant find a link too it I read about the study.
Hmmm.....

So a betta in a tank with a filter will live for at least twice as long as a betta in a bowl?

Hmmmm...I didn't realise that.

All my past betta's have lived in bowl/large vase type glass containers - and I had one little guy who lived for so many years we lost count of how old he was...we started affectionately referring to him as 'The Survivor Fishy' :)

I don't want this little guy to die prematurely though just because he doesnt have a filter set up :shock:
They can live without a filter but you have to do a lot more water changes. They can also live without a heater depending where you live Bettas prefer warmer water than most fish but average home temp is too cold and water is cooler than air.
Hi, welcome to the forum.

Tail biting solutions is rather an individual thing, there's really no 1 solution that will work for every individual betta. Perhaps the most common (in the sense that it works for most bettas) is putting them in a sorority - say 1 male to 4 or 5 females. BUT this method has it's risks.

A female may be killed; females might attack the male if he becomes less aggressive due to constant non threatening contact; they may spawn (not really a problem). You have to know your betta's general character. I'd take a 10g or more tank, heavily plant it so that some areas are hard to get to plus hiding places if you wish. I don't really mind which goes into the tank first. Sometimes they all move in at once. I've noticed that my tail biters will be busy chasing females instead of his own tail.

Other methods such as cutting the fins very short only works for few. Most eventually will bite their fins once it's long enough. Food is also not the problem - all of mine get the same amount of food. Perhaps what you're trying will work for your little friend.

In any case, good luck. Hope he lives a long and happy life (I'm sure you're going to spoil him) LOL

IAL make the fins stronger might help stop him a bit.
I have a 3 tailbiters, and I know its the filter, if it is too strong, they get stressed, and if they are long finned males, they cannot get around in the current as well, one of my fishy's a HM male, I had for 6 months with no filter, only a bubble stone, recently started biting, yes his fins got very long, and I had no choice to use a filter, the pump broke, and I used a filter until I could replace the pump, and this fishy is in a 5 gal. now my VT is doing it too, because of a filter, and my newest fishy another HM in a 2.5 gal, and again the filter causing biting problems, my fishy is now in a bigger tank, with only a bubble stone, and is already making improvement. My other fishy;s are female, so no probs there, and my other VT no probs, no filter.
Welcome to the forum and to the wonderful world of Betta keeping...

Enjoy your stay...
Interesting fact there are more than 50 Betta species.
So a betta in a tank with a filter will live for at least twice as long as a betta in a bowl?
Many people who keep their bettas in tiny, cold bowls have reported that their fish have lived for 2X as long. However, they most likely were not happy or healthy fish. If they didn't die from disease due to improper care, it is possible the reason they live for so long is because the cold water slows down their metabolism or at least that's the theory anyways. Is it true? I'm not sure but I know with trapdoor snails - ones kept in warm water have shorter life expectancies then those in cold water.

A betta in at least 2.5 gallons with weekly water changes and a heater (depending on where you live) will be a happy and healthy betta. A filter is not needed if you do 2 water changes a week (one 100% water change with gravel cleaning to remove any poop or whatever that has fallen into the gravel) and one 50% where you just change the water. I don't think its worth the effort to have a filter in anything under 5 gallons - at least not for me. I don't have enough outlets for that so only 10G and up get filters. A few times, I had to keep moving my fish around to try and find one that could be on the side of the tank with the filter and NOT bite his tail ( my 10 gallons are divided to hold 3 males in each tank). If it wasn't the filter then the reflection they saw of themselves in the tank glass caused them to bite. I ended up having to keep the light off so they didn't see their refelction anymore.

If you can figure out why he is bitting, you may be able to stop it. Sometimes they bite cause they are bored or something stresses them out. I have one VT that rips his fins to shreads every time I change the water :evil:, some just don't like big heavy tails and some bite cause they can.

Does he have alot of decor or is the tank bare? If its bare, try adding more stuff and at least one plant that reaches the surface. It may help if the reason for the bitting is boredom or stress from feeling exposed.

I remember reading about a lab study where the tank fish lived double the lives of bowl fish.
Perhaps we have found the trigger!

Saturday 10/11/12:
Amazon fish related order arrived this morning.
Completed 100% water change with Seachem Prime and Stress Coat.
Added 2 x new silk plants (one looks like a penny wort replica the other has tall long fern type leaves) and also added a small zoo-med betta floating log with feeding hole.
Put fish back into his tank with the newtoys – he was calm, seemed happy, floated around calmly-looked to be exploring his new decorations but did not seem stressed by any of it nor did he seem to be avoiding any of the pieces. Within 5 minutes of being put into his bowl he was even swimming straight through the floating betta log, inside, outside, all around – took a pellet through the feeding hole - he even used the bulb of wood on the outside to rest his nose on and seemed very happy with it.
Probably about an hour later I was watching him from the couch – he swan inside his log and then the next minute he was thrashing round in circles like Ive never seen him do before anywhere in his tank.
I moved from the couch and sat by his tank, watching and my hubby sat watching from the other end. After another few minutes he swam back inside the floating betta log – it looked like once he was inside he then relaxed and tried to settle down inside it – his fins floated/expanded/branched out – and he immediately then started thrashing round and round in circles, like he was trying to attack his fins – perhaps because they hit the inside of the log and he thought he was being attacked by something or…?
I took the floating betta log straight out if his tank.
Then put in a new floating lily pad instead. (almost exactly the same as the one he has always had in there)
It looks like there is new damage now to the longest part of his back fin and also a chunk out of his tail fin – but it is really hard to know for sure because I have not seen new damage before and his tail is pretty ragged already from past abuse).
I plan to watch him carefully over the next week – now that I have seen this new frenzied tail attack behaviour, it seems quite feasible that his little house that he had always had but that I did take out of his tank a few days after he moved in with me, was the tail biting trigger. I had removed that little house and never saw him showing any interest in his tail until I gave him the floating betta log – which once inside that it I could clearly see what was happening.
I am slightly concerned now that his new silk plants that branch out through his bowl…which I had hoped would give him new ‘hiding’ and playing and exploring stimulation could in fact trigger the same behaviour – as he swims by the leaves they could touch his fins and set him off on the circling tail attacks – but I have not seen that reaction caused by the leaves yet and he has been swimming in between them and all around the bowl today – something to watch out for though.
At present it appears the behaviour is only triggered when his fins are touched inside a ‘confined space’.
Hubby is concerned that now he does not have a ‘house’ or ‘cave/log’ he can go into whenever he wants that will not be able to get enough ‘dark time’ to sleep properly or enough when he needs to. Hubby has suggested that if he does has this specific confined space tail biting trigger and that is the reason he attacks it all the time/never lets it grow back properly – that perhaps we need to start covering his bowl with a towel/sheet or something to make it dark for him…in place of giving him a ‘cave’ to go inside. I want to do more research to see if that is necessary.

Any thoughts or suggestions from members are welcome!

Thank you :)

PS: I have Attisons betta pellets being shipped from the IBC. Still yet to find supplier who will ship here and has Omega One or New Life Spectrum pellets tho.
