I have a 55 gallon tank with about fifteen demasoni cichlids. One of these stopped eating about three weeks ago. It would hide and come out only on occasion. I thought maybe it was carrying eggs in its mouth. Today it was acting the same until this evening when it first laid on a rock for abt 20 minutes, the swam around the whole tank in a weird way...it swam as if it were lazy or drunk...obviously I'm just using those terms to describe what it best looked like. It let the bubbles carry it up and then slowly came down a few times. After a short rest it started swimming and jerking and twisting and even ran into things...only to fall to the floor of the tank and sit there lifeless. Did I just witness the horrific death of this fish when I was hoping for fry? Help a guy out.
