yahoo here too. Both of mine take frozen brine and mysis and even chase it down and eat it as it drifts along the bottom. Mr. mandarin taught Mrs. mandarin how to do it, too! But I agree, it is atypical, and it took the male over a year to figure it out on his own. Plus I suspect they probably could not survive on it alone because they'd be out compeated by the other fish. I think a big part of why they fare poorly has to do with how they're caught. Used to be almot exclusively cyanide or other temporary paralysis-rendering chemicals, but Matt tells me they're using tiny barbless spears now through the tail muscle to catch them.
