Here is my old ass amphilophus lysoni that sulked for almost two months after his lady friend passed. I threw everything from frozen, fresh, and treats into his tank and he wouldn’t touch a thing and really thought he would just pass away. I had a handful of their spawn in the tank that was fed daily using 3mm Northfin pellets with the weekly dose of frozen krill, bloodworms, brine shrimp, and plankton and just like that he ravaged the hell out of just the bloodworms then immediately started to eat daily after. God knows why he didn’t eat but he’s 12 years old this year, looks a little raggedy but is still active and eats daily. Here is after two months of not eating, you can really see the sunken stomach.Does anyone here know more or less how long can a fish like this go without eating?
This is the part that concerns me given that its been over a month now.
I tried reading online but almost everything i found said a couple weeks or longer for bigger fish. However mine is not particularly big (5-6").
