Hi I noticed one night this Fish was near the top of the tank in the middle breathing really really hard. The other fish avoided them or chased it away and there were no signs of stress on any other fish (breathing, black barring on the peacocks, clamped Finns, not eating, flashing, excess slime coat, etc.) the ONLY symptom on ANY fish was the heavy breathing on the one Mbuna. I fell asleep and in the morning it was dead. I pulled it out and since it hadn't been touched by the other fish I checked the gills. NO Gill tissue was left except the Gill plate. absolutely no trace. It just had bare bone visible. I have done a water change and dosed with salt but I really need to identify the culprit so I can prevent this from happening again!
THANK YOU
