They're currenly in a 15 or 20(?) gallon, but we have a 55 gallon housing goldfish and we'll be moving them in there, once we move the goldfish into a 110 gallon. I'll build them an area of land once they get it, or I'll see if I have anything in my basement that I can build them something now.

I know one of the turtles, Sheldon, already somehow escaped once. He was just walking around the house as if nothing, lmao.
Their diet is about 2-3 pieces of commercial food a day each, and they get romanian lettuce, carrots. And they get crickets here and there as well.
I've been switching their diet here and there though. We got Sheldon from a petstore and his shell had white patches all over it, I've been trying my best to get it back to normal. It's been a slow proccess but he's getting there.
