Is it safe to put a brick in an aquarium? I am working on making a rock formation at the back of my tank for some african cichlids. I found a brick that has 1.5" diameter holes in it's side. I thought that they might make interesting caves for the fish to hide in.
 
I'd think brick is similar to terra cotta as far as chemistry goes, and there is a whole lot of terra cotta harmlessly sitting out there in tanks…
