Thank you very much! The Powder Blue is fairly new (couple of weeks) but he seems to be doing very well. He is in my SPS system which has a lot of room, a lot of rock to graze on and very clean, stable water parameters. I have been feeding him frozen Mysis (soaked in Zoe for extra vitamins to help keep his disease tolerance up) and Omega One flake. If your tank is new I wouldn't attempt a Powder until it as least 6 months old! They do have a tendency to be disease prone if stressed. I have a friend that has a UV stearlizer that has kept one for a couple of years. Thet key is to give them plenty of room and a stable enviroment! Take care!
