i had to pull one of mine recently.. he wasnt able to get any food even when i tried to target feed him. normally i would just let nature take its course but with out food they just get weaker and weaker and smaller and smaller. so i have him in a second tank and i am feeding him double the amount as the others along with a soon to be tank mate mrs. pike cichlid, they just both now need to get some size. i was suprised that it wasnt that easy to get him eating again.
