I'm at a loss. I've tried keeping them stocked with goldfish and tried getting them on other food and they're still small. I've had them for almost 2 years and they're still less than 6 inches (2 kelberi and 1 azul). They kelberi will eat shrimp, but the azul just spits it out. Is my best bet to starve them and get them acceptive massivore or what? I also have and ocel that won't eat anything but live, but I'm not as concerned. My orinos grew a lot faster than these guys. I should probably do more water changes, but I generally do 50% every week. They're in a 75 with a 10" black arowana. I'm wondering if I should get them off live completely first or throw them in with the orinos and then do it. The smaller orino eats pellets, but the larger one will only eat shrimp.
