"Goniopora sp. require PERFECT water conditions, the proper trace elements and the habitat must match its requirements. In general, the Red form of the Flower Pot Coral does better in an aquarium than other Gonipora sp. However, any damage to the meaty section of the True Red Flower Pot Coral almost always means a lost specimen. One can only do this Goniopora Coral justice by leaving its care to the experienced hobbyist with the expertise and time to keep the coral properly."
My husband bought one of these things. I made him return it! I've read when they die (and even the best tanks kill em after a few years at longest) that they can crash your tank. They are awesome to look at, but I'm not willing to kill it or my other tank members. If your water isn't perfect it wot come out and it won't live. Sorry
