Creating layers in a tank?

[Spartacus]

This may sound silly, but I've always wanted to create a layered environment for my axolotl tank, such as having some small ledges they can hang out on, to give them more space away from each other.
I would want them to be temporary of course, so I was wondering if anyone has ever done this or has any suggestions?

I know for reptiles, they can sell little ledges which stay up with a magnet on the inside and one on the outside. Is a magnet safe underwater? Would it be harmful to my babies?

I just think it would be cool, and it could have some plants growing on it, maybe even draping over, I don't know. If anyone has seen anything like this, or can think of ways it can be done, please share

Sounds like a cool idea idea, would love to see a photo

As for the magnet, I'm not sure if they would leech metals into the water, but magnets for cleaning fish tanks are quite common.

Depends on how they're set up- if they're sealed, they're okay. If not, maybe avoid. You could also use stones to create a table which you could top with slate. Can't wait to see what you come up with!
