Was fine this morning, came back from the store and it looked like this. I just added in an urchin today, has been on the opposite side of the tank guaranteed! Also added in a few CUC today as well as an acan. Not sure what exactly is going on. It has some stuff coming out of its mouth I sprayed a little of it away. I don’t have my params atm but if it was dying would it have changed that quick?? I was only gone an hour!
