your bgk will find the food if its hungry enough. when i first got my bgk i had it in a tank with my pictus catfish who is a vacuum when it comes to eating, the pictus would have half the food eaten before the bgk would know theres food in the tank. but there was some territory issues between them so i moved the bgk in with my guittarita and they get along fine. i've read on other ppls threads that some bgk will get picky and only eat one kinda food. so far i've lucked out and mine is hungry for anything. it gets live guppies every few days to keep it busy for the night. seems to take it a while to hunt down the little suckers but when i wake up in the morning its sporting a fat belly and theres not a guppy to be found.
