Once settled and kept in cool water C. interrupta does well and is a bold Centropyge. Ask anyone who's imported these guys though from Japan and they'll tell you they have issues and are far from bulletproof (Joculators on the other hand are pretty darn close!). It doesn't help that most of them are large either... I cannot stress how important it is with these guys to get a conditioned fish though... This all contributes to the high price of this fish, including very high freight costs out of Japan... Juveniles are collected deeper and very hard to come by and in high demand... of course all of this makes it a great species for aquaculture, and Frank at RCT will work with them again!
Venusta is as far as I know currently classified under Paracentropyge, which is a valid genus now...
