Princess Anthias - Pseudanthias smithvanizi

Anthias are closely related to the often large and aggressive predators known collectively as Groupers but have much more peaceful temperaments. Within the Anthinnae subfamily, the temperament can still range from very passive and docile to downright bold but most are still peaceful compared to many of the other fish reputed to be "aggressive" and "territorial". Most anthias are shades of pink, red, orange and yellow; colors that help them blend in in the deeper waters many are found in. Size can also range between species but most anthias are under around 7-8 inches in length and the majority available in the aquarium trade are around 3-5 inches in length.

Anthias are planktivores and feed primarily on zooplankton, tiny animals found in the water column. They benefit from several small feedings throughout the day rather than one large feeding. A healthy microinvertebrate population in the aquarium with a constant supply of food items like copepods and amphipods is beneficial but most anthias can be weaned onto frozen and prepared zooplanktons, Cyclop-eeze, mysis shrimp, baby brine shrimp and similar items.

These fish are best kept in small harems of one male to several juveniles or females. If the aquarium cannot handle a group of 5 or more fish, most anthias can be kept alone or occasionally in a male-female pair. Suitable tankmates for anthias would be peaceful fish that will not harass these docile fish or outcompete them for food. Stressed anthias have been known to jump from an aquarium. Anthias are Reef Safe and are not normally known to bother corals or invertebrates.
