I've got a young male motoro. Nice and fat but I'm not sure that he is eating well. Explores everything - krill (thawed, not dried), blood worms, earthworms - but I'm not sure he s eating. Krill looks is all chewed up but he leaves it in pieces (legs/head - maybe he is eating the belly?). Can't get live black worms until Thursday. Is this typical? Any tips? Not interested in silver sides at all. Happy to take food from my fingers.
