What Randall Anthias look like
Pseudanthias randalli, commonly known as Randall's Anthias, exhibits a vibrant coloration characterized by a predominantly pink to orange body with a yellowish hue on the dorsal fin and a distinctive purple stripe running along the lateral line. Adult males can reach a maximum size of approximately 3.5 inches (9 cm), while females are generally smaller, measuring around 2.5 inches (6.5 cm). Sexual dimorphism is evident, with males displaying more vivid coloration and elongated dorsal fins compared to the more subdued hues and shorter fins of females. Defensive adaptations include a laterally compressed body that allows for agile swimming and quick evasive maneuvers. Unique morphological features include a well-developed lateral line system, which aids in detecting water movements, and a set of small, sharp teeth adapted for feeding on zooplankton.
Behavior & temperament
Randall's Anthias are typically found in small to moderate-sized schools, exhibiting a social hierarchy where dominant males establish territories and maintain a harem of females. They are pelagic fish, often swimming in the upper water column above coral reefs. Breeding behavior includes a unique courtship display where males perform intricate swimming patterns to attract females. Their temperament is generally peaceful, although males can exhibit territorial aggression towards one another during breeding seasons. They are known to be active swimmers, often darting in and out of crevices within the reef structure.
Diet & feeding
In the wild, Randall's Anthias primarily feed on zooplankton and small invertebrates. In captivity, they require a varied diet consisting of high-quality frozen or live foods, including brine shrimp, mysis shrimp, and finely chopped marine foods.
Behind the name
The genus name 'Pseudanthias' derives from the Greek 'pseudo' meaning 'false' and 'anthias', referring to the resemblance to other anthias species. The species name 'randalli' honors the American marine biologist John Randall, who contributed significantly to the study of reef fishes.
