We have five RES, all about two years old. Three females and two males (based on length of toenails and shelll size), ranging from 10 inches to 6 inches. The two largest are in a 55 gal, and the three smallest in a 40 gal. Each tank has a Zoo Med slider hood with heat lamp, basking lamp and reptisun lamp. They eat Reptomin sticks (and don't like anything else!) daily. They seem to be very healthy--lots of active swimming, eating well, and hard, not deformed shells. Don't see a lot of bulging, either.
I know they're overcrowded--just learned about the 10 gallons per inch of turtle today. We have two main problems: filtration and basking.
Filtration: each tank has a Fluval 404 Plus internal filter, which supposedly moves 240 gal/hr. Doesn't keep the tank even remotely clean--and they knock it off its suction cups, so it ends up on the bottom, further impairing its function. (We feed in the tank--it really seems to upset them to move them out, and then they won't eat.) Water level in both tanks is at least 12 inches.
Basking--We need some sort of island. The heaviest turtle weighs about two pounds--the suction cup islands aren't strong enough, and big rocks collect a red algae, which gives them conjunctivitis. They also need a ramp--the littlest ones can climb up, but Samantha, the biggest, is just too big to climb up without a ramp.
We live in northeast Ohio, where the winter temps can get below zero and (and frequently remain in the 10-20's all winter). People have suggested that we build a pond in our backyard for them, and I'd be happy to do it next summer, but what about winter? Even if they hibernate, is it too cold here?
Any suggestions/advice would be gratefully appreciated! We really enjoy having these turtles and want to give them the best habitat we can.
