I just purchased a piece of live rock with a red mushroom on it. It seems to be pretty opened up in my tank, and doing alright (bought it on Saturday). I havent been able to find a solid answer to the feeding question on red mushrooms. Should I be target feeding it or should I just let it feed itself through floating particles/food in the tank and photosynthesis? I also haven't noticed it catching any of the mysis/brine I feed the fish, probably because its in an area of lower water flow.
