well ive had my motoro about 2.5 yrs now and he always roams along the bottom like a vaccum cleaner when i feed my fish. he usually sucks up about 20 pieces of krill befoe hes done but this time he only ate about 3 pieces. anything i should be aware of or just give it more time? i also have had bichirs and cichlids in with him and for the most part they all grown up together. cichlids dont bothher him but the the bichirs always must have thought his tail was a worm. even though i never seen them bite him his tail is always trimmed right were his stinger is. its never bothered him before but now im starting to wander?
