The first time I did a Scoly it didn't work out so well for me. Since then, I've learned about amino acids, trace elements and actually feeding them. I currently have 4 Scoly's and they all seem to be doing well, I plan on moving them to a slightly shadier portion of the tank. Personally I love them but I have a rule of thumb with all corals, if "Master" is in the name I"m not interested in buying it. They are beautiful just too expensive for me to take the chance with.
