ever since my betta magnum died, the betta sushi that lived in the other half has been acting wierd. he curls himself in a ball and just lays somewhere between decorations. he constantly has a full belly (hes been feasting on water fleas) even though all the waterfleas have been gone for a week. hes even hiding himself and not responding when i walk in..... he shouldnt be close to the end of his life because i got him a year after magnum. he doesnt even want to chase the shrimp and corys that he now shares his tank with, he wont flare or anything.
