Should I put it in the sand or just a little higher than that? For now I have moved it to sit on the rock right in front of the six line wrasse in the picture that I took. So we will see what results I get from that. Does anyone know what I can do about the green algae or whatever it is that has grown on the skeleton tips. Could that be from too much light? Will/Can it go away now that I've moved it down and maybe it won't be a breeding ground for that green stuff anymore? I sure hope so, that bubble coral is my favorite, but its also been the biggest pain!
