a couple of months ago i switched from freeze dried krill to frozen krill and i would break it up into small pieces and scatter it around the tank because my other fish liked to nibble on it too.but he kept getting bigger so i figured he was going around and gorging himself on it.so i cut back and he kept on getting bigger.so then i would only feed it to him every 3-4 days and he still got bigger.sunday night his belly was huge and monday morning he was dead.i had had him 10 months and his growth was nice and steady until i switched to the frozen krill and then he really started to grow,i mean his whole body,not just his belly.
