Options for single piece 3d flooring?

[takagari]

Since I am converting a large tank to use for rays, I was thinking of going bare bottom. But dislike the look
I am tempted to cut floor tiles. and may do this as well, have people trying to glue these in or do you just leave them free, for easy cleaning?

at the same time, doesn't anyone make a 3d/carpet type flooring for cages?

Or other great ideas anyone may have?

I had rays a few years back and I just painted the bottom of the tank.
