i don't know if any one on here knows much about turtles, but I was wondering if my tank is big enough for a Mississippi map turtle and a Florida red bellied slider. (They're compatible). Thetub is 4 feet long, 20 inches wide and the water can be filled to about 9-12 inches. (Or less if need be but from what I've read, deeper is typically better). Also would they both have to be female? I know I can't do two males but would it be possible to have one female and one male? Thanks.
