tile in aquariums?

[tankbuster69]

Ive seen many ray owner and breeders with tile or granite floor, i have a small slab of tile thats black and white and would like to offer it as a breeding slate for my hybrids. The nice is much better looking than a simple piece of slate rock but is tile safe for the aquarium?

most natural stones are aquarium safe. I have seen granite in aquariums. I use slate for mine. If it has been grouted, mortared, or has the adhesive mesh backing on it before, that stuff is toxic.

im not sure what it is exactly, its just marbled with brown, white and black. Have any guesses?
