This is my first time here and I am looking for some information. Basicly, what I'm looking for is what is the smallest size tank I should have for a single RES?
As I have a 40g tank that has no occupants that used to house fish and was looking into housing a turtle.
As far as equipment for the tank, this is what is on it. glass lids (I have a screen to use for the basking light), Penn Plax Cascade 500 and Whisper 60 filters, and a heater. I'll be getting the basking light once I'm sure the tank will work with a turtle. And there is no substrate in the tank, but I have rocks to build a basking island.
I have seen how large they can get, but how can they be sexed at a young age to get a male? and whats the largest tank size for them?
Thanks
