Care
Yellowback Anthias are knownfrom the upper parts of outer reef slops, drop-offs and outer reef lagoons, ata depth between 4-40m (13-131ft). This is a species that shoals in sizeableaggregations as it feeds on zooplankton in the water column, with one male fishoverseeing a large harem of females. This is a fairly delicate species that issuitable for advanced aquarists only. In the confines of the aquarium, it isbest to keep either a solitary specimen, or else a group comprising of a singlemale and at least 8 females. Unfortunately, smaller groups will result insquabbles, where the weakest fish is likely to be picked on and prevented fromfeeding, eventually succumbing to being bullied by the others. These largeshoals should only be considered if the tank is of XXL proportions "“ if thetank 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 foodcompetitors or with docile species such as firefish. Conversely, ensure thattheir tankmates are not overly large, belligerent species either, or theYellowback Anthias will feel intimidated. Many have found that these fish dobest when introduced into a tank that already contains a well-established shoalof less-aggressive anthias species, as this helps to stimulate the feedingresponse and facilitates their own acclimatisation. Yellowback Anthias areusually perfectly safe in a mature reef set up, typically swimming out andabout in the open water areas and ignoring sessile invertebrates. A varied dietis a must to keep the fish in good health and for them to display their vibrantcolouration. Ideally they will be fed small amounts several times per day (seebelow). An attached refugium cultivating copepods and amphipods can also reallyhelp to provide a steady, ongoing supply of nutritious live food to keep thisactive planktivore content. Powerful filtration and protein skimming, plus agood maintenance regime are essential for maintaining optimal water qualitydespite the heavy nutrient input. As these fish inhabit areas of moderate tostrong currents in the wild, they require fairly brisk water movement in thehome aquarium - a high level of oxygenation at all times being of utmostimportance. May also be seen on sale as Evan"™s Anthias or the YellowtailGoldie.
Feeding
In the wild, this species is constantly on thelookout for food, taking zooplankton from the water column. Due to their fastmetabolism, 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 meatyfoodstuffs such as Mysis shrimp, vitamin-enriched brineshrimp, finely choppedkrill/prawns etc. in addition to zooplankton preparations (containing copepodsand rotifers) which are often available in either frozen or refrigerated forms.Many will also take dried foods in time.
