My Lobo is turning whiter everyday. I have tried to feed it multiple times but it does not eat. Water parameters are fine. You can see that everything else in the tank is ok. I tired feeding it reef roid, coral frenzy powder and pellets. I even put the pellets by its mouth. Does anyone know what is wrong with it and what to do. Posting an enlarged picture of the lobo and of the tank. Whe I brought it, it had a deep redpurple color. The other half of it is not what but is now dark black purple. Are both sides dying? I have a 32 gallon biocube with LED lights that came with the biocube. I have changed water 15% weekly but I am going to cut down on the water changes. The alkalinity was fine and the phophates according to the store a week ago. If it is dying should I remove it from the tank?
