I have this same stuff in a couple of my tanks. My ebjdxbgjd pair lay eggs on it. I have had it in the tank for 6 months no problem. It is a little factory for my taste but I do put it on the bottom glass and surround with sand. Like a solid base. Then put my other rocks on top.v01rider said:i am wondering if these would be ok to put in my tank?
here is info on them
