Well Oakley and Hissy seemed to be outgrowing their tubs so Ash and I decided to get them some bigger ones that we saw at Target. They are 15qt rubbermaids and I love them. The bottom isn't flush but is convex so the heat tape sits right on it unlike the others we had that it was concave and sucked into the tub. They aren't tall but have a good bit of floor space. If anyone is needing to upgrade to a larger tub and wants a fairly shallow one with plenty of floor space these are great. We actually got them at Walmart for like $3 a piece which was AWESOME! lol. Next to upgrade is their hides because they both seem to be "turtle-ing" them so Ash is gonna pick up 4 new medium hides and a couple of bigger, round water bowls.

PS. Hissy will get her photoshoot tomorrow because I barely have any pics of her.
