I had two fish that would gulp for air only after eating. Pellets, nori and mysis. They would gulp for a hour or so, depending on how much they would eat. I use the word gulp, as bubbles comes out the gills. I already lost two fish that did this. They did this for months before the just stopped eating and died. I have a third fish doing the same thing. He started when the other two was still alive. I treated the tank with prazi twice. Back to back doses with the skimmer off. I searched the internet for gill and intestinal diseases but could not find anything which describes what is going on here. I know I don't have an oxygen problem. I always have the return just under the water surface so there is plenty of oxygen. So any one have any ideas?
