this is gonna sound really bad, but i recently purchased a brain coral [maybe like a week ago], and it was fine 1st, but later on the same day tissue began to unstick from it. if hammer is still doiing fine, i think this thing is really diying. 1/2 of the flesh is gone already and he doesnt except any food. not getting any better, actualy much worse every day. any suggestions. the hammer is kinda coming back to life, everything else in the tank is amazing.
