Cryptocentrus cyanotaenia

Cryptocentrus cyanotaenia – Blue-Spotted Goby

Cryptocentrus cyanotaenia, known as the blue-spotted goby, is a calm and discreet bottom-dwelling fish that catches the eye with its small bright blue spots scattered across a beige or light brown body. Its attentive gaze and stationary attitude near its burrow make it as useful as it is pleasant to observe.

A Fascinating Symbiotic Fish

This goby lives in symbiosis with a shrimp of the Alpheus genus. This natural association is remarkable: the shrimp digs a burrow in the sand and maintains it, while the goby provides surveillance and alerts to danger with its tail movements. Together, they offer a captivating display of interspecies cooperation.

A Peaceful Fish for Sandy Reefs

The Cryptocentrus cyanotaenia appreciates tanks with a sandy substrate and rocky areas to establish its burrow. It is very territorial around its shelter but remains peaceful with other species, especially if it has its own space. It can be kept alone, in pairs, or with its symbiotic shrimp.
