Brahm Eviota

The Brahm Eviota is one of the tiniest vertebrate species available in the marine aquarium trade, reaching a maximum size of just 0.8 inches. This diminutive goby was among the first Eviota species to be successfully captive bred by Biota Marine Life, a milestone achievement that made this obscure micro-fish accessible to nano reef enthusiasts worldwide. Its translucent body displays subtle orange-red markings that become more vivid under quality aquarium lighting.

As a hermaphroditic species, Brahm Eviota possesses the remarkable ability to change sex depending on social dynamics within a group. This reproductive flexibility means that any two individuals can potentially form a breeding pair, which is advantageous for both wild populations and captive breeding programs. In the wild, these gobies inhabit sheltered coral rubble zones and the branches of staghorn corals in shallow Indonesian reef flats.

Despite its minuscule size, the Brahm Eviota is a surprisingly engaging aquarium inhabitant. It perches on rock surfaces and coral branches, making short darting flights to capture passing micro-organisms. A dedicated nano reef with stable parameters and a healthy population of copepods is essential for long-term success with this species.
