I have a baby betta, currently he is in a 1/2 gallon tank. He hasn't been able to eat much since I don't have daphnia, and bloodworms and pellets are too big.
He has been staying on the bottom of his tank, and recently has been "standing" on his tail fin. When he attempts to get air from the top, he swims in spiral swirls and it looks like he is having a seizure or something. I'm very concerned and don't know what to do.
Water is clean, and conditioned. Water is at 75 degrees, I'm trying to warm it without shocking him, but I don't have a heater.
Any information would help!
