maybe [another] clam in the lower spot? torch coral maybe? star polyps? a nice frag of zoos?
While I feel that my previous experience in this system with a clam was a success, at this time, I don't feel that this would be a good idea as for one the polyclad is still in there to the best of my knowledge, and I would like to wait until I can get halides. There are some zoo's nearby, so I dont really want to add more.
for the high up spot, maybe some pagoda cup or favites.
never really thought about a pagoda . . . . I always thought they were high lighting demand corals (halides)
