So I have a 6-6 1/2 inch Senegal Bichir living in a well-established 55 gallon tank. How long should this guy be able to survive without being fed? For context, I have quite a few other fish (I ensure it's not overstocked), but this Bichir is the only purely carnivorous fish I have, so he won't eat the flake food that I put in an automatic feeder. I normally feed him once a day, but should he be fine for a couple weeks? I don't really want his pellet food to clog the feeder, thus causing everyone else to starve if he would have been fine anyway. Thanks!
