The peach anthias is found in the wild in great numbers, and in an aquarium it needs to be kept in schools of at least 10 to 12 fish. Because it needs a lot of swimming room it should be kept in as large a tank as possible, with a 100-gallon tank being the minimum size. The school should consist of one male and all the rest females, but because the peach anthias is hermaphroditic, if the harem loses the male the dominant female will become a functioning male. Males are distinguished by having a bright red dorsal fin and very extended ventral fins.
The peach anthias can be difficult to acclimate to an aquarium, and it should never be put with fish that are at all aggressive. It is excellent for a reef tank, and will appreciate the strong water movement, as well as having plenty of places in the rocks and coral to hide in when it needs to. Getting peach anthias to feed can initially be a problem, and it may require live brine shrimp (enriched) before it will accept other frozen or prepared foods. Because it is constantly looking for food in the water column, it is a good idea to feed it very small quantities, but many times a day.
