i think all mandarins eat frozen food, if the other fish would give them a chance.

my pair were the only fish in my tank and within a week of getting them they were already eating frozen food.

now when i put the syringe of food in the tank to thaw the male will actually come up to the top to suck food right out of it.

I Think its ok. My single mandarin is housed with 2 skunk clowns and 2 tomato clowns. (200g). You will probably have to start target feeding the mandarin because the clowns are much faster eaters. It's great it's eating frozen! I feed mine bloodworms from a turkey baster.

What kind of clowns are you thinking? My skunk clowns host a sebae anemone and the tomatoes a bubble tip. There are lots of compatibility charts online and indivdual fish are different and don't always follow the rules. I have read ocellaris clown are one of the least aggresive.

just grabbed these two yesterday http://www.canreef.com/vbulletin/showthread.php?t=84331

super health and active, and no agresstion at all toward the mandarins

I also have no problem with my mandarin pair and my black ice clownfish pair. Before that I had fancy white and regular occelaris and still no problem.
