Gastone - few came down with fungus infections and few recent ones I picked up perished all within five days. (but I think this was mostly due to a delayed flight) They seem to have very low tolerance for stress and aggressive tankmates. Ever since seperating them to their own 30 breeder "species" tank, they've been doing great. I'm running MJ900 for moderate flow (they don't seem to like the heavy flow all that much), and running an underrated heater to help with their coldwater preference. I've seen many others keep them in a mixed reef with success however, but in larger tanks 100+.
freeze - I've been just feeding them like I would feed any other anthias - several times a day in small amounts of flakes, and every other day with mysis and brine. They don't seem to go for cyclopeeze or any other small frozen food.
