Hi Everyone Im new at this hobbie which Im getting pretty hooked up very fast. I currently have a 40 gal hex aquarium, with a Magnum 350 filter pump one protein skimmer and im about to receive an HQI 150 watt metal halide light fixture I also have about 25 lbs of live rock some brown and green polyps. one I believe leather coral and some mushroom coral I currently own a Marron Clown, a Cardinal Fish a Bi-Color Blenny a Copperband Butterfly and a Crab now my question is with my Copperband lately ive seen that he is breathing heavily what could be causing that. That is my main Concern right now and also what else do i need to add to my aquarium as far as equipment. I would really appreciated it any comments with the heavy breathinf of my Copperband Butterfly Fish.....
