Neon Pygmy Goby

The Neon Pygmy Goby is one of the smallest vertebrate species kept in the marine aquarium hobby, reaching a maximum length of barely one inch. Its nearly transparent body reveals internal organs and the delicate skeletal structure beneath, while subtle neon-like highlights of pink, orange, or yellow shimmer along its flanks when caught by aquarium lighting. This ethereal, almost ghostly appearance gives the species a unique and delicate beauty.

Belonging to the genus Eviota, which contains some of the shortest-lived vertebrates on earth, the Neon Pygmy Goby has a naturally brief lifespan of approximately 6 to 12 months in the wild. Even under ideal captive conditions, hobbyists should expect a lifespan of roughly one year. Despite this brevity, the species compensates with rapid maturity and frequent spawning, making it a fascinating subject for those interested in the biology of micro-vertebrates.

This species is exclusively suited to nano reef aquariums, where its tiny size and minimal bioload can be properly managed. A 5-gallon nano tank provides adequate space for a small group. The Neon Pygmy Goby spends its time hovering near rocky surfaces and coral branches, darting out to capture passing zooplankton. Its extremely small mouth necessitates the provision of micro-sized food items such as live copepods and rotifers for optimal nutrition.
