I just bought a huge rock water fountain carved out of a real boulder for my tegus (LOL!). It's really cool, and I specifically asked if they were safe for potable water. The guy said yes it was made to keep fish in it. There are pictures of these fountains with fish in it, but at the store they only had plastic fake fish.
In particular, there is one bit in the fountain spout that is filled with some kind of rock putty, presumably to fix a crack. I asked him he said it was safe but I don't think he really knows.
So after researching, basically there is no way to know for sure as I don't know the rock type nor the putty used. So I thought perhaps I can test it somehow.
Do you guys know if I were to put some goldfish or something in there and they don't die after 3 days, does that mean it is safe for my tegus to drink from? I don't know anything about fish though so they maybe die anyway nothing to do with the rock.
I thought about drilling the putty out and replacing it with reef safe epoxy but worry that by messing with it it would "release the poisons" and make it worse.
Why does our hobby attract so many paranoid types like me?
