That last picture isn't a turtle, but she's my other little helper.
I don't think I ever posted a picture of it, but there's a small hole cut into the right side of the tank, you can see it somewhat in post #43 in the second picture, that's the cat hole for getting to their kitty litter box, and there's a divider under the tank to prevent them from getting to the pump and other things under the other side. Now I just hope my cats are smart enough... 2 of them probably are, one of them....... would be good friends with Tempe (the yellow mystery).
