For Christmas, my daughters each got a Betta Fish from Santa Claus and 5 gal. Tanks. My wife liked the fish so much that she got one too along with another 5 gal. tank. While I have been cycling the tanks (fishless method) we have been keeping the Bettas in bowls. So now I was suddenly the care taker of 3 Betta fish.
We change the water every day. Treat the water the day before and let it sit overnight near the bowls so the temperature is the same and then do the water change with that water the next day. For now we are keeping the Bettas in a room that we have a heater set for 75deg. (The 5 gal tanks all have heaters set at 82 when they get there)
The day before yesterday, while changing the water, my wife's fish got spastic and had what looked like a seizure.... then he swam lopsided and was not swiming well.... from what we could read it sounded like swim bladder dissorder so we started down the diagnosis and treatment path of fasting and trying to serve him a piece of cooked pea should he be constipated but he saddly died yesterday. I have no idea what I did wrong and was sure I was taking care of him better than if he had been left in the cold pet store with infrequent water changes but now I am very frustrated that somehow my lack of experience killed this poor fish.
It's worse.... last night while changing the water with one of our two remaining Bettas one of them freaked out when I put the net in the water and before I could even get him into his new water he also did a crazy swim and then acted like he also might die from a siezure ..... eventually he calmed down and made it thru the night. Today when my wife tried to interact with him he also went crazy... almost jumping out of the bowl and then appeared to die..... my wife called me in tears thinking he was actually dead and then called back to say that he had revived and was upright again and breathing but we don't think he is doing well and I don't know why
There are no signs if ick or any ailments of the fins or skin visable.... but he goes to the bottom.... could he just be stressed from the water changes? What else could this be? I have to change the water but when I do it feels like something is going wrong.... I have been doing this for weeks now and all was good up until the last couple of days and I can't think of anything I am doing differently.
Please help me before my ignorance kills another fish!
Thanks for any help you might be able to offer
