Ok so, my dad's friend acquired a betta and two parakeets. The previous owners moved out 3 days ago and left them behind and never came back. So now I have a betta that doesn't look so well. The water was really cold, maybe 50*F and it is laying on the bottom of the bowl. I don't want to add warm water because I don't want to kill the fish. So I put it closer to the heater and the water is warming up. It is probably 60 now. His fins look a little frayed too. I know nothing about bettas nor their health. I don't want the poor guy to die. I can't put him in my other fishtanks because I have other fish in them. So what should I do? Think it will live?
