Eviota storthynx
Family: Gobiidae ยท Gobies
Also known as: Storthynx Pygmy Goby, Storthynx Dwarfgoby, Palauan Pygmy Goby
The Storthynx Eviota is among the most diminutive vertebrate species available to aquarists, reaching a maximum size of just 0.7 inches. This incredibly tiny goby from the reefs of Palau was first captive bred by Biota Marine Life, a significant aquaculture achievement that brought this obscure micro-species into the hobby. Its semi-translucent body displays subtle reddish-brown to orange markings that become more visible under magnification or quality macro photography.
As one of the smallest fish species on Earth, the Storthynx Eviota exists at the very limits of vertebrate miniaturization. Its tiny body contains a fully functional skeletal, muscular, and nervous system compressed into a package barely larger than a grain of rice. In the wild, these gobies inhabit sheltered coral rubble areas and reef crevices in Palau's rich marine environment, where they feed on micro-organisms invisible to the naked eye.
The Storthynx Eviota is a social species that thrives when kept in small groups. In a well-maintained nano reef with stable parameters and abundant live copepod populations, a group of these micro-gobies creates a fascinating display of natural behavior. They perch on coral branches and rock surfaces, making tiny darting movements to capture passing organisms. Due to their extremely small size and specialized care requirements, this species is best suited for experienced nano reef hobbyists.
Storthynx Eviota are micro-predators requiring the smallest available food items. Provide live copepods, frozen cyclops, and live rotifers. A refugium producing live micro-organisms is virtually essential. Their extremely tiny mouths cannot accept any standard aquarium foods.
Storthynx Eviota must only be kept with the smallest, most peaceful tankmates. Any fish over 1.5 inches may prey on them. Best in species-specific nano tanks or with other Eviota species and micro invertebrates like sexy shrimp.
Check CompatibilityStorthynx Eviota mature quickly and can spawn frequently in captivity. Pairs deposit microscopic egg clutches on hard surfaces. Biota Marine Life first achieved captive breeding of this species. Larvae are among the smallest of any fish and require live rotifers and phytoplankton.
