Christy, The Threadfin Anthias, Nemanthias carberryl, will do best if housed in a medium to large-sized aquarium with nonaggressive tankmates and plenty of hiding places. It is best kept in a group consisting of one male and eight or more females. Strong water movement and good water quality are prerequisites for keeping this sensitive species, while live foods (e.g. brine shrimp) may be neccessary to induce feeding. Introducing this fish into a tanik that already contains an established shoal of less aggressive anthias may facilitate its acclimatation. This species can be kept in either a shallow or deep-water reef aquarium. Scott Michael

Also, the way they act in a fish store is often abnormal.

Try posting the question about cloudy eye on either Fishnet or reefcentral. You should recieve some qualified advice.
