First time with corals, picked up a Candy Cane, Zoas and a Green Emerald Mushroom...candy cane cam on a stake/plug and is looking kind of brown.. and im not sure what to do with him so i just stuck the plug into the sand for now....will it be ok or should i somehow put him on a rock? the mushroom somehow came off the plug in transit and i panicked and glued (horrible glue job i know...) him back on the plug and onto a rock but now its kind of folded up on itself...
