feeding firefish gobies... advice??

[Tau2301]

When I feed the Kyle Mysis (I think thats what everyone is calling it) I shave it from the frozen block with a very sharp knife (Ginsu - just kidding). I don't rinse, just put into the tank still frozen.

This gives me the small particules my smaller fish can eat. My corals also seem to perk up after I feed the Mysis this way.
