Question for all DIYers, need opinions please.

Ok here is the deal.I have a 10 gal tank that i would like to turn into a bath tub for Kiku. Here is the problem, unless it looks like a rock, she wont relax and stay in it. I need to find a way to make the bottom, and possibly about 2 inches of the sides, look and feel like a "rock". Without making it too heavy , cause I also use it as a "travel home" too. Any ideas?????

ALL ideas welcome...PLEASE, Im racking my brain and im at a loss...

Lowes sell insulation foam used to fill in large cracks. Im sure you can line the bottom with that and then make it look like a rock. I seem to recall several post on here about making rock ledges and walls with the same stuff.
