About Neon Goby
Tiny Caribbean cleaner goby that sets up cleaning stations and actually picks parasites off larger fish — the captive-bred equivalent of the wild-caught cleaner wrasse, without the ethical concerns. Excellent in pairs.
Elacatinus oceanops, commonly known as the neon goby, is a species of goby native to waters of the Atlantic and Gulf coast of North America from Florida to Belize. This cleaner fish can be found on coral heads at depths from 1 to 45 m. This species grows to a total length of 5 cm (2.0 in). This species can also be found in the aquarium trade.
Notes from the editors
What it looks like. Slender, mostly black body with a vivid neon blue stripe running from snout to tail. Small — adults reach only 2 inches.
In your tank. Sets up cleaning stations and actually picks parasites off larger fish — the ethical and reliable captive-bred alternative to the wild-caught bluestreak cleaner wrasse. Multiple specimens can be kept and will pair off naturally.
Care notes. Peaceful and reef-safe. Lives in cracks and small caves; provide ample rockwork. Will breed in captivity in established systems.
Sourcing and feeding. Captive-bred and widely available ($20–40). Strongly preferred over Labroides dimidiatus for cleaning duty — survives well in captivity where the wrasse does not. Carnivore — mysis, brine, small pellets, parasites picked from tankmates.
Care info is a starting point, not a guarantee. Individual specimens, water chemistry, and tankmate dynamics vary. Verify against multiple sources and adjust to what you observe. See our terms & disclaimers.
