Definately don't NEED a 200+gal tank for your RES,i have 4(3m 1fem) 3yr old RES in a 90 gal.------------btw i do plan to get rid of 2 if i can find a good home.
but unless you plan to do 3 water changes a week(like i do)i wouldn't recommend trying this.
-the males will only grow about 6 to 8"s and females around 12"(carapice diam.)
-filters should be internal and OR canister
-feeding,lots and lots of greens for the young ones(lettuce,spinach)
-i also feed frozen krill,crayfish,turtle pellets
-1 basking area per turtle,should be about 90degs. use uv lighting
btw you can save swimming space by buying the suction cup basking area
sorry don't have much time,i'm at work
