no anthias ARENT hardy. If you get them healthy you are doing good. they seem quite predisposed to popeye, and worms. You shoudl worm them when you get them for sure, and QT them to get them eating well. I've had a few just never eat and die. this isnt uncommon, but out of the 8 of my origional hutchiis, and the 7 of my origional flames i have 5 hutchiis, and 6 flames..
