I know these are peaceful fish but i just got 1 about 9" long from my lfs seems they grow to fast for what most people consider a large tank> i have him in a 150 now and he likes bashing and moving anything around. My question is whats the best thing to feed them unlike my ID sharks and white tipped columbians he dont seem at all interested in blood worms or brine shrimp or the shrimp pellets. I dont want him to starve and also how big will he get i plan on moving him to a larger tank with my IDs once they all clear 12"
