The Peach Anthias is a fantastic looking saltwater fish, but unfortunately, may not be the best choice for most marine aquarium keepers. They can be quite finicky when first introduced and are susceptible to most saltwater fish diseases. Proper acclimation and the use of a quarantine tank is a must with this species.
To help make them feel secure you should provide lots of live rock for hiding. In the ocean, they are commonly found on the outer reefs where there is very strong water movements and providing strong water movement using multiple powerheads in your aquarium will most likely be rewarded with increased activity from this fish. Open tops could spell trouble with these beauties because they will jump when frightened.

These anthias may do alright with multiple peach anthias buy may get aggressive with other smaller sea basses. They should be able to handle being kept singly if needed. Avoid keeping them with larger, more aggressive species such as Lionfish and Eels. They may become snack food for these predators.

When first introduced to your marine tank, you may have problems getting the them to start eating. Try frozen brine shrimp cubes or live foods. Once acclimated, try to give them a varied diet of live, frozen, freeze-dried and vitamin-enriched flake foods.
