Cosmic Nano Goby – Eviota lachdeberei
A fun and beautiful nano goby with a dark body and white dots on the belly and a row of white spots on the dorsal ridge. Two vibrant blood red blotches at the base of the tail stand out with complementing subtle red markings in the eyes and edges on the scales of the ventral side of the fish. This unique coloration makes the goby look like a cosmic scene of black space, white stars, and red nebulae.
Mature males can be identified by the first four dorsal spines being elongated.
This pygmy goby is perfect for small nano and pico aquariums. They are incredibly peaceful and do well in small groups. They can be found guarding nooks and crannies in the rock scape and darting around searching for food.

The Cosmic Nano Gobies are stunning. Their coloration is truly unique, resembling a miniature galaxy. They’re very active and enjoy exploring the rockwork. I’ve kept them in a 10-liter tank with other small fish, and they’ve stayed peaceful and healthy for over six months.

I was drawn to the goby’s striking red and white pattern. They’re small but lively and add a lot of visual interest. I noticed the males have longer dorsal spines, which helps identify them. Good for a small tank with minimal space.

These gobies are a joy to watch. They dart around the crevices and seem to take pride in their territory. I’ve kept a group of six, and they coexist well with my shrimp and other small fish. Very easy to maintain.
