Hey guys, I was visiting my LFS today since I just started putting together a FOWLR tank and saw a really impressive looking black sun coral...In the tank I only have two small butterflyfish right now and don't plan on adding much more except maybe a tang or dwarf angel...Now I know that butterflyfish aren't reef safe but since sun corals remain closed when the lights are off, would the butterflies really be able to do it any harm during the day or would they actually go looking for food in the middle of the night when the sun coral opens? Oh and btw, I actually have a small black sun coral in a different tank so I know what's involved in their care...this one I saw at the shop today was really sizable and since it was a little bit bleached (likely from lack of proper feeding) I'd probably get a really good price and could just nurse it back to health. Has anyone tried this? What do you guys think?
