Hi everyone, I no many probably won't post on here but I just wanted to give it a try. I think I'm going to get a turtle in a few months but don't no much about em. So any help or advice will be thanked very much. So so far I'm wondering if a 20 gallon tank is big enough for a adult painted turtle???? Its a old fish tank we found last year in the basement. Its in very good condition still but I'm wondering if it's big enough.?!. If not where can I get a cheap glass bigger tank? Also what food is recommended or best for it? I will probably have more questions as I go but for now I think these are the major ones. If not please I would love any and all advice and comments! Thanks everyone!
