Care

A small Caribbean goby with green vertical bands. The list describes it as a burrowing species. Its size makes it a good choice for a nano reef with rockwork and a sandy area; tank size here is an estimate. The sources give no water figures, so the temperature, pH and salinity shown are general marine aquarium guidance, not species-specific: 24–27 °C, pH 8.1–8.4, specific gravity 1.023–1.026, with stable, well-filtered water. The article calls it lively and entertaining but territorial towards its own kind in small tanks, so keep one or a pair. Sources: Wikipedia, List of marine aquarium fish species (en.wikipedia.org/wiki/Listofmarineaquariumfishspecies); Wikipedia (en.wikipedia.org/wiki/Elacatinusmultifasciatus). Checked October 2026.

Diet

Not covered in detail by the sources. Offer small meaty foods such as frozen copepods, mysis and brine shrimp, and fine pellets, in small portions more than once a day.

Breeding

The article says it starts life as a female and can change sex to form a pair, so two fish usually become a male and a female. No captive spawning details are given.

Compatibility and tank mates

Reef safe. Keep singly or as a pair; males of the same species may squabble in small tanks. Avoid large predators.
