OK. I'm planning for the future. Looking to get some zoas in my tank, not sure which ones yet. But as I'm reading it seems I get mixed signals as to what to feed them. I read don't feed just good light. Then I read to spot feed. Then I read that it depends on the zoas. Then I read that the longer and thinner the tentacles, the greater role feeding plays and non-feeders have short stubby ones. So what do you guys do. Feed or no feed?
