Compared to the occurrence its compatriote C. melanodactylus, this species found in large numbers. The relationship is mutualistic, with the species occupying a niche similar to that occupied by the more colorful Trapezia species . Cymo species , however are typically drab in coloration, and usually have a layer of algae growing on their carapace. Very common and is considered a coral symbiont , with the caveat that such symbiosis are a tradeoff between the coral and the crab, the coral gains protection and house cleaning services while giving up a few polyps, mucus and captured/ settled food particles in exchange for those services. A healthy coral Editors: Ramin Ketabi;Shahla Jamili (IFSRI) should have no problem repairing or replacing lost polyps, but again, in an aquarium environment, an eye should be kept on the coral for excessive damage being done due to the coral being unable to recover as fast as or faster than the damage being done by the crab. As obligate coral symbionts, the survival of this species is directly associated with the conservation of coral reefs, which are under threat from coastal development and land reclamation resulting in heavy siltation, dumping and pollution. Members of the order Decapoda are mostly gonochoric. Mating behavior: Precopulatory courtship ritual is common (through olfactory and tactile cues); usually indirect sperm transfer. Habitat: Coral Reef; Marine; depth range 0 - 17 m Distribution: Persian Gulf (Iran, Kish Island) , Red sea, Madagascar, Seychelles, Somalia, Red sea, Fiji, Japan, Maldives, Sri Lanka, India..
