Unhappy sick betta

I have a 2.5g divided tank with 2 male bettas that don't really seem to care about each other, the tank has been set up for a few days expecting the fish and last night they were finally put in.

all night they were swimming around and seemed to like it, but this morning one of them was laying on the bottom of his side of the tank and started leaning to one side.

I read that this might be swim bladder related and could be caused by overfeeding, we fed them once last night before bed, and again this morning around 8am. about 2-4 pellets each.

the water was treated and left standing for about 2 days before adding the fish, and the tank has a small filter (all came in a aqueon betta starter kit) that doesn't seem to bother the healthy fish on the filter side of the divider.

I don't have a heater but I plan on going out to get one today, even if it isn't necessary for a tank this small, I still need one to start my 10g this summer when I'm home from school.

2.5 gallons for 2 Bettas is actually too small. They really should have a minimum of 2 gallons each. I mean, some people say 1 gallon per fish is OK, but just picture a gallon jug of milk. This is the fish's entire world!

You didn't mention any dechlorinator for the water. Do you have any? This is a MUST HAVE item. The chlorine in tap water can and will kill your fish. Letting the water sit out is not enough to remove it all. Prime is a great brand of dechlorinator.

You say you fed them between 2 and 4 pellets each. I'm not sure if you just grabbed some pellets and dropped them in, or counted them. I personally put in a single pellet at a time when feeding, and no more than 3 per feeding, twice a day.

It might be the swim bladder, but a little more information would help. Can you get a clear picture? Is your fish swimming at all?

he died within the hour I was at class, I'm still curious to what might have caused this. He was acting 'interesting' last night before bed, he was taking small air bubbles from the bottom of the gravel and spitting them out up top. I assumed this was him trying to make a bubble nest.

this is the tank that I bought:

the water was at room temperature and might have warmed a slight amount from the lamp on the tank until I turned it off around midnight.

I used the water treatment that came with it and allowed it to sit for about 2 days before buying the fish, they seemed healthy at the time of purchase yesterday and were very active last night until I went to sleep.

Well, if you just got him yesterday it is very likely he was ill when you got him. Sadly it happens fairly often. They can seem OK, but quickly decline. This happened to me not long ago. :/

If you kept the store receipt, you should be able to get a refund. You will probably have to bring the dead fish to the store in a baggie as proof.

I do suggest just getting a refund and NOT getting another fish. The 2.5 gallons is OK for one Betta, but small for two. This is my opinion anyway.

I wish you the best for your other fish!! <3

Please invest in a heater before you buy another fish. They are tropical fish and need water warmer than room temp.

got a thermometer and heater, it was at 74 degrees before I even started up the heater and now I have it holding at 76. I got an ADF, a large decoration and a few live plants to give them both some hiding places.

I also got multi-test strips and all of them seem to be in the safe levels except the nitrate 2 showed a hardly noticeable pink.

I'm not sure what a normal hardiness is for bettas but it showed at 75/soft

If you've got an ADF please read this thread. and please get a larger tank. An ADF needs at least 3 gallons per frog, and the fish at an absolute minimum needs a gallon or two. Your tank is far too small for both.

Edit: I don't mean to sound mean but I'm trying to help you make your new friends thrive instead of just live. :)

Hey how is your other betta doing? Make sure that he don't get sick from the other one. I really like the idea ,that i read someone wrote to quarantine betta before you put them together. Always make sure you have extra 1 gall if you have new betta. A lot of time betta is already sick from the store and you don’t want to contaminate the tank.

The same is about live plants. Always quarantine them before you put them in the tank. Live plants can carry disease.

Also i like Wystearya point about feeding. 3 pellets per feeding is maximum, i feed my bettas 2pellet x 2 daily. Well i give them snacks sometimes. And always put single one make sure he eats and it don't sink to the bottom of the tank because it will contaminate the water or remove it if he refusing.

Also for 2.5 gall you need to do 1-50% and 1-100% water changes if you have one fish in it without ADF. Also I would make 50% water change since you have sick fish in it.

Talking triple sulfa & bettafix for sick betta

Hi: I'm really new here, but still I thought I would share what I've had happen to my betta. I have 2 females, a red and a pink, who lived in harmony for about 10 months or so in a shared, not devided 5 gal. tank. About 2 or 3 weeks ago I noticed that my red one had fog on one of her eyes so I began treating the entire tank with triple sulfa. Seemed to have worked almost perfectly. This past week I saw a lot of white patches on the red one and the pink one kept attacking it. I think the spots are lost scales from being attacked. So I bought a 2 gal. for the pink one and left the injured red one in the larger tank. Yesterday I began treating with 'Bettafix'. The white spots are slowly lifting from her skin. I'm not sure if I should continue with the triple sulfa at the same time as the bettafix though. Until I know this I will now continue with the bettafix. So far the bettafix looks promising. It is mostly melaleuca. She is coming out a bit today, but is still not eating. She was eating when the pink one was in the same tank. I am soaking some anti-bacteria medicated fish food pellets in garlic guard in the hopes that she will eat later. Hope something here is helpful for your betta.

Mendmyangels - be careful with bettafix. Many people say its a miracle drug but alot of people say it killed their betta. If its working, I would continue using it but follow the dosing instructions. Its main ingredient is a tree oil that can damage the breathing organ. As long as you don't overdose on it, you should be ok. Plus 2 females can't really live together. you need 5 or more to establish a pecking order and you should have at least a 10 gallon tank. Even then, there is no guarantee they will not fight to the death.

It's possibly the fish was sick when you got him. It happens alot, especially if he came from a petstore or walmart.

I would clean out the tank just to be sure the sick fish didn't leave any nasties in the tank. I would also remove the divider and keep just one betta in it. His tank is his entire world.
