Description edit
On average, a mature male ranges from 2.2 to 4.9 centimeters (0.9–1.9 inches) in length, while a mature female is 2.1–3.4 centimeters (0.8–1.3 inches) long. It has two dorsal spines, 26–29 soft rays, and 25–27 anal soft rays. The males develop bristles on their caudal peduncles when they reach sexual maturity.[2][1]
Ecology edit
This species occurs in coral reefs at depths of 2–12 m (6.6–39.4 ft). It is usually found among soft corals and is believed to feed off of both the coral polyps and the coral tissue. To survive, it needs water temperatures of 28.1–28.7 °C (82.6–83.7 °F) and dissolved oxygen concentration of 4.45–4.47 mL/L (4450-4470 ppm).[2][1]
