  • Temperature: 23–27°C (73–81°F)
  • Salinity: 1.020–1.025
• Care Level: Easy to moderate, suitable for beginners with basic marine tank knowledge.

Origin and Distribution

The Blue Neon Goby is found in the Western Atlantic, particularly around Florida, the Bahamas, and the Gulf of Mexico. It thrives in shallow coral reefs and rocky substrates, often at depths of 1 to 15 meters, where it engages in symbiotic cleaning behaviors.

Colors and Markings

This species is instantly recognizable by its slender body and a bright, iridescent blue stripe running longitudinally along its black body. The fins are mostly transparent, adding to its delicate appearance.

Tankmates

The Blue Neon Goby is a peaceful species and thrives in community tanks with similarly calm fish. It pairs well with:

• Clownfish
• Blennies
• Cardinalfish
• Peaceful wrasses Avoid housing them with large predatory fish that may see them as prey.

Care Requirements

To keep the Blue Neon Goby healthy:

• Provide a 10-20 gallon tank minimum with live rock for grazing and hiding.
• Maintain excellent water quality with a stable temperature and salinity.
• Use moderate lighting to mimic their natural habitat.
• Regularly test water parameters to ensure stability.

Diet and Feeding

An omnivorous cleaner fish, the Blue Neon Goby feeds on small invertebrates, parasites, and plankton in the wild. In aquariums:

• Offer high-quality frozen or live foods such as brine shrimp and mysis shrimp.
• Supplement with marine flake food or pellets.
• Feed small amounts 2-3 times daily.

Gender Differences

Males and females are visually similar, but during breeding, males can appear slightly slimmer. Behavioral differences may also be observed as males court females.

Breeding

The Blue Neon Goby is relatively easy to breed in captivity. Key considerations:

• Use a breeding pair in a separate tank with ample hiding spaces.
• Maintain stable water parameters (temperature around 25°C).
• Females lay eggs on flat surfaces, which the male guards until they hatch within 5-7 days.
• Feed larvae with rotifers or fine plankton for optimal growth.
