Doing weekly tank maintenance this morning I noticed my baby Norman's Lampeye swimming normally but appeared to have food stuck in its mouth. Posted this pic to another group and the only response I got was that this is a parasite. Either columnaris or lamphocystis. I removed the fish and put him in a paraguard bath but he was struggling and died within a few minutes. None of the other inhabitants appear to be infected. This Lampeye was born in this tank and there have been no new additions in months. I do weekly water changes and I'm very attentive to the tank. Only recent change was I moved a powerhead to increase water circulation because I saw the beginnings of staghorn algae. Water parameters PH 7.4, dg&kh 14, ammonia, nitrite, nitrate all good. This tank is almost a year old and heavily planted. I also have 11 cpds, 1 guppy, 3 Norman's lampeyes (now), mystery snail and a small colony of neo caridina.
