I was thinking of getting a Poseidon aquarium decoration and try to get a coral to grow on it. The coral I was thinking of are Clove polyp, Daisy polyp, and Zoa. I wanted a coral that didn't grow insanely fast and lays down tubes so you can still see some of the decoration under it. I was going to glue it down on a piece of stacks rock and put the coral around the decoration on the rock.
