Red Sea Anthias

Overview

The Red Sea Anthias (Pseudanthias taeniatus) is a vibrant, reef-associated fish endemic to the Red Sea. Often found in social groups, these small, colorful fish are a common sight along coral outcrops and steep reef slopes.

Distribution & habitat

This species is restricted to the Red Sea, where it inhabits seaward reefs and areas with consistent water movement. They are typically found near the bottom, often congregating around coral colonies or rugged reef structures.

Appearance

These fish exhibit distinct sexual dimorphism. The body is generally orange-red, though coloration can range from light orange to deep red. Males are typically larger than females and may display a longitudinal white or yellowish stripe along the body. When displaying, males can intensify the blue and white tones of their markings.

Biology & behavior

Red Sea Anthias are diurnal, gregarious fish that live in well-organized hierarchies. A single male typically maintains a harem of 8 to 15 females. While they are generally peaceful, they can be slightly territorial, particularly when establishing or defending their social structure. They are often observed swimming alongside other anthias species, such as the more common Pseudanthias squamipinnis.

Feeding

They are omnivorous with a strong carnivorous tendency, feeding primarily on small organisms found in the water column.
