Smooth marble ok for tank?
I found a lovely moss green marble soap dish (5.5"Lx3.5"Wx0.75"H) at Goodwill today for a buck. It does not look or feel like it has ever had soap on it -it still had the original store tag on it. I would like to use it as a feeding dish in the 75g. This dish would be great to keep the pellets contained and not rolling off into the substrate (it is slightly concave). Right now all fish but the cories eat pellets off a flat rock.
Is marble safe for aquariums?
