ok, first I am going to say welcome to swf.com it is a wonderfull site to get answers and to research. You are new and making the classic mistake that most new hobbiests make. You didn't research before buying. What kind of lighting do you have, what kind of anenome do you have, what size tank, how long has it been running, what are your ammonia, nitrite, nitrate, ph and salinity readings? How long did you acclimate it? All of these things need to be answered first before we can answer your question.
