Collin’s Fairy Goby | Tryssogobius colini

The Collin’s Fairy Goby (Tryssogobius colini) is a small, peaceful, and relatively uncommon reef goby prized for its delicate appearance and graceful swimming behavior. Featuring a translucent body with subtle yellow coloration and striking fins, this beautiful species is an excellent choice for peaceful nano and reef aquariums. Unlike many bottom-dwelling gobies, Collin’s Fairy Gobies often hover just above the substrate or near rockwork, making them fascinating to observe.

Collin’s Fairy Gobies thrive in mature, established aquariums with stable water conditions, plenty of live rock, and sheltered areas where they can retreat when startled. They are best housed with peaceful tankmates that will not intimidate or outcompete them for food. Offer a varied diet of small meaty foods such as copepods, enriched brine shrimp, finely chopped mysis, and other appropriately sized frozen or prepared foods. Their delicate appearance, peaceful temperament, and unique hovering behavior make them an excellent addition to established nano reef aquariums.
