I just adopted a new Map turtle who is about 2 yrs, she came from a Reptile Rescue. I don't think she has ever been in really deep water before. The level of water she was in at the reptile rescue place wasn't too deep cause she could stand and stick her nose out of the water. I have her in a 90g that is almost filled to the top, only about 3inches short of being completely full. When I put her in the tank she sat at the bottom for a bit and then when she needed to breath she stood up, stretching and stretching till she realized she's gotta swim to the top. She kinda flails around and doesn't seem to know how to float. Right now she sitting on top of the power head for the under gravel filter.
It's weird cause my Res was in a 30g before and water was only standing depth of his body, when I moved him to the 90g he was really good at swimming right away and was swimming up and down in the tank for hours he was so happy. I'm kind of worried about her drowning, but if I lower the water they wont be able to get onto the ramp of the above tank basking area.
