hi im getting a turtle setup with a red bellied turtle. its a 20 gallon tank and the turtle is 2 years old. i need some information on them like max size...
well, your going to need to get a much larger tank, the largest red bellied turtle was over 15" and make sure your setup has a basking spot w/ uvb/uva lighting. i recommend an above tank basking area to utilize the most of your tank for swimming.
Well you should have been doing you research but I am not going to lecture you on that.
Red bellies get WAY too big for a 20 gallon tank. You will eventually need a 150+ gallon tank depending on the dimensions. A pond would be even better though if you can do that. at 2 years it should have already outgrown a 20gal so something is definitely wrong. post pics and stats of the turtle if you can so that we can get an idea of the problem.
