ELLO! My brother and I have had an oxydoras niger catfish living in a 180gal with a larger red tailed cat, a shovel nose, 2 longfinned oscars, and 2 flowerhorns. Everything I've read has said that these oxydoras niger cat fish are big and active eaters and grow fast. We have has this guy for a year and he doesn't move around too much and when he does its usually in the middle of the night. So my question is, is there a reason that this chap is much less active than what I read about? Do we just have a lazy fish?
