I think It should be enough light for clams, It pretty much lights up the entire room to the point where I dont need to turn on any other lights at all. So I'm guessing if it provides enough light for me, it should provide enough for anything I put in there
and a clam would be pretty damn cool in there.
As far as coral, I'm really confused, I want some frogspawn, Hammer, zoa, ric, and thats about all I know for sure right now. Feel free to drop some suggestions, as well as placement. Once I get my aquascape up for the rocks, i'll take pics and then you guys can tell me where would be the best possible locations for em. I dont want them crowding or killing one another.
