Care
Yellowback Anthias are known from the upper parts of outer reef slops, drop-offs, and outer reef lagoons, at a depth between 4-40m (13-131ft). This is a species that shoals in sizeable aggregations as it feeds on zooplankton in the water column, with one male fish overseeing a large harem of females. This is a fairly delicate species that is suitable for advanced aquarists only. In the confines of the aquarium, it is best to keep either a solitary specimen or else a group comprising of a single male and at least 8 females. Unfortunately, smaller groups will result in squabbles, where the weakest fish is likely to be picked on and prevented from feeding, eventually succumbing to being bullied by the others. These large shoals should only be considered if the tank is of XXL proportions "if the tank is of average size, it really is best to house a single specimen only. YellowbackAnthias are relatively peaceable. They should not be housed with direct food competitors or with docile species such as firefish. Conversely, ensure that their tankmates are not overly large, belligerent species either, or the Yellowback Anthias will feel intimidated. Many have found that these fish do best when introduced into a tank that already contains a well-established shoal of less-aggressive anthias species, as this helps to stimulate the feeding response and facilitates their own acclimatization. Yellowback Anthias are usually perfectly safe in a mature reef setup, typically swimming out and about in the open water areas and ignoring sessile invertebrates. A varied diet is a must to keep the fish in good health and for them to display their vibrant colouration. Ideally, they will be fed small amounts several times per day (see below). An attached refugium cultivating copepods and amphipods can also really help to provide a steady, ongoing supply of nutritious live food to keep this active planktivore content. Powerful filtration and protein skimming, plus a good maintenance regime are essential for maintaining optimal water quality despite the heavy nutrient input. As these fish inhabit areas of moderate to strong currents in the wild, they require fairly brisk water movement in thehome aquarium - a high level of oxygenation at all times being of utmost importance. May also be seen on sale as Evan's Anthias or the YellowtailGoldie.
Feeding
In the wild, this species is constantly on the lookout for food, taking zooplankton from the water column. Due to their fast metabolism, they require feeding in small amounts several times per day (i.e.at least 4 times) if they are to maintain good health. Offer a variety of fine meaty foodstuffs such as Mysis shrimp, vitamin-enriched brineshrimp, finely chopped krill/prawns etc. in addition to zooplankton preparations (containing copepods and rotifers) which are often available in either frozen or refrigerated forms. Many will also take dried foods in time.
Breeding
This species has not been bred in the home aquarium.
