He is an adult turtle, he's not smaller than 4" (although those are incredibly popular here )..for the first week I had him, I did not have a water heater and he wouldn't eat. The water temp was around 70-72 degrees, and what I've read is RES like the water about 80-84 degrees. According to a website if the water is too cold it dosen't stimulate him to eat. He does have a ledge he can get up on and bask, however I have never seen him on it. If I place him on it, he goes right back into the water. I usually take him out in the evenings and he sits with me or roams around, just to get him used to me.

I've tried bloodworms too (I have some for my betta fish..), he didn't even take a glance at them.
