पृष्ठीय रीढ़ (सम्पूर्ण) : 55 - 58; पृष्ठीय सौफट रेज़ (सम्पूर्ण) : 0; गुदा कांटा: 0; ऐनल सौफट रेज़: 39 - 40; जानवरों की रीड़ का जोड़: 58 - 61. Caudal with convex outer margin (Ref. 6885). Color very variable- may be light to dark gray with olivaceous overtones, brown to dark brown with or without reddish overtones, or purple to almost black. Females are less varied in color, but show more pattern, usually having green grayish backgrounds with brownish reticulations, or dark brownish backgrounds with subdued reticulation. Belly pale. In the males, the cockscomb and under surface of head are pale, rather yellowish, and without speckling. In the female, the head is more speckled and mottled. There is a gray bar across the base of the caudal peduncle. At breeding season, the male develops bright orange colors on its anal and pectoral fins, and reddish on the caudal and dorsal fins (Ref. 6885).
Facultative air-breathing (Ref. 126274); Usually found in intertidal areas under rocks (Ref. 2850). May remain out of water under rocks or seaweed (Ref. 31184). Green algae is an important food item but may also feed on polychaete worms, crustaceans and mollusks (Ref. 6885). Breathes air (Ref. 31184) and can remain out of water for 15-25 hours if kept moist (Ref. 51276).
Spawning individuals are territorial. The female guards the egg mass deposited between rocks and shells by bending her body over the eggs. She fans the eggs by moving the posterior part of her body (Ref. 6885). In the aquarium, males mate with several females (Ref. 39998).
