Frogspawn, hammer, and other LPS
like torch, acanthastrea, brain corals, etc. would be fine with 4x 54W HO
T5. Anemones probably won't... JMO, maybe someone else will disagree. SPS
is probably a no-go as well.
I've personally heard too many horror stories about nems taking a walk around the tank and stinging corals, or worse, getting chopped up in a powerhead and nuking the tank. HN1 and I have been staying away from them for those reasons. There is no guarantee that a clown will host them anyway. Our clown doesn't host anything even though we have a large frogspawn that resembles a nem.
