Hi everyone. I am having an issue with one of my yellow tail acei. She is the tank boss of an mbuna only tank. There are 15 mbuna in total, most are juveniles. Over the last four days I have observed her shaking her head and having some kind of spasm. I am not confusing this with the shaking that happens when fish are trying to instigate mating or to warn others off. From my observation this is happening approximately once every few hours and often when she is swimming alone with no other fish nearby. She will be swimming along then come to a jerking stop, have a spasm which involves shaking her head and then go forward, stop with a jerk again, shake head and then return to normal swimming. If she was human I would say she was having a fit of some kind. I cannot see any visual indicators of disease on her. She is active and eating well. There have been 2 recent changes that I have made but I don’t see how they could be affecting her. 1) 5 days ago I moved all my mbuna from my 4ft to my 5ft to give them more swimming room and more rocks/caves. The tank is being filtered by their old canister with the mature media. I did clean this but only the same as I always do when doing my regular maintenance. 2) I added 3 new juveniles to tank. BUT, I observed this behaviour in acei BEFORE they were added. I am at a loss as to what is happening with her. She is the only one doing this. And this was not happening in old tank. My water parameters are good 0 nitrite, 0 ammonia, 10 nitrate. I only feed them food specifically made for mbuna i.e. veg or spirulina based pellets and flake as well as shelled peas and zucchini. It could be purely a tank boss thing - but my gut is telling me that something is wrong with her. If it was a parasite wouldn’t they all be doing it? What could it be? Any suggestions would be greatly appreciated. Thanks everyone.
