I was taking the advice I got here and instead of using cork bark as an underwater dock for my new tank since it's floaty I was going to use one of those suction cup soap dishes. The thing to me is..they just seem way to small for my Koopa

I was trying to find a corner shower shelf, one with suction cups, that I can use instead. I wanted to make sure it was plastic or acrylic..not metal or anything..and I'm just trying to make sure I find one thats completely safe. I think whatever I get I would have to turn it upside down because everything has a lip on it...so far the best thing I found was this:

But I didn't know if the holes in it would cause a problem..or if it was bumpy if it would irritate her belly (plastron?).
There's also alot of ones like this:

But I don't think the material is meant to be continuously underwater or that it's the best thing for her to be laying and sleeping on.
Help? ^^;;
