and how long can they go without food? i have been weaning a gar off live food for about two weeks and he absolutely refuses to eat anything else. (market shrimp, sinking carnivore pellets). i tried putting a piece of shrimp meat onto a mono-line and waving it around in his face. it sparked a response at first, but he spat it out. after two or so strikes, he stopped. the gar hasn't eaten in two weeks now. will it starve to death? there is also a clown knifefish in the same tank as him who refuses to eat prawn. the knifefish hasn't eaten in almost 3 weeks. anyone has any idea on how to get them to eat?
