Hello All,
I have recently inherited a 5 year old female RES from a co-worker who moved to CA. My co-worker did not have an adequate setup for this size turtle, but I'm doing my best. She is alone in a 55 gal tank, with Reptisun UVB, and I got a dock for her first thing because she never had one. She seems worlds happier now, her colors are better and her scutes are going - I've also been taking her outside to bask in our yard. But, for some reason she cannot seem to drop below the surface? She tries, but she is so buoyant that she is constantly floating unless she is on the dock. Do RES have an air bladder like fish? Or is there something I can feed or give to her to help her impairment. Thanks for the help!
