My husbands little brother gave us his painted turtle. He's had her about 6 years and she isn't in good condition at all. Her shell has algae and white spots, she isn't shedding properly and until today she hasn't had a space to bask in a few months at least. I have her in the same tank she came in until we can afford to buy her something bigger.
I know the white is probably fungus is there anything I can get to treat it without going to a vet?(we are a little pressed on money right now) also what else can I do to help her get better?
She's outside right now, so she can get some sun. But will keeping her in a dry in closure be better for her shell? Also what else can I feed her besides pellets. Is it the same as RES?
Thanks in advanced I attached a picture of her.
