I believe I may have figured out what's killing my fish. I fed them tonight and as one of the fish went after a piece of food as it grabbed the food, shook, and chewed I saw a bunch of what I first thought to be sand come out of its mouth. Found this very odd coming from an Armatus. I grabbed a net to fish some of this stuff which floated around much more then sand would. No luck, too small. Grabbed a breeder net and nabbed some. Appears to be eggs. Found a cluster of 5 stuck together. Camera can't get pics, too small. Am I indeed looking at the eggs of Dactylogyrus? Can someone help me out by confirming diagnosis and recommend course of action? I'm under the impression that Prazi is all I need, BUT seems the eggs are extremely tough to kill. Can someone recommend a dosing schedule? Prazi once a week for a month? Thanks so much for any assistance!!
