I really dont know much about lighting or corals but just wanted to keep some lowlight corals after i get my fish settled in for a few months. I dont want to upgrade the lighting fixture because its an eclispe hood and if you replace that then i would have to get another top, lighting fixture and pwrhead to supplement my filter but I might eventually when i get more money. The light is an 18" flourescent and from what i understand you need 3-5 wph for a lower light corals. I just want to lively up my tank with something my clowns could host inl. I was thinking of frogspawn and mushrooms and Zoanathids. I really dotn know the care requiremetns for this or if their even lowlight corals but any help would be greatly appreciated. I really dont want to add any food for the corals but anyways, thanks for all the help, I couldnt have gotten this far without you all.
