I found some rocks near my house and decided to try a few out. I tested them with vinegar and then boiled them for about an hour. They look similar to others that I have seen used, but I want to make sure.
My tank is currently cycling with some tetras, so I guess they will let me know if they are not safe. I have a couple more rocks that are the same type that will go on the opposite end of the tank. They will be hiding spots for my JD when I put him in the tank.
Can someone tell by the pics if they look ok?
