In the vast realm of aquatic life, there exists a tiny, yet captivating creature that has captured the hearts of aquarists worldwide: the Red Neon Eviota Goby. This diminutive fish, hailing from the tropical waters of the Indo-Pacific region, boasts an array of remarkable traits that make it a sought-after addition to marine aquariums.

What is the Red Neon Eviota Goby?

The Red Neon Eviota Goby, scientifically known as Eviota pellucida, is a species of goby fish belonging to the family Gobiidae. These tiny creatures typically measure between 0.5 and 1.5 inches (1.27 to 3.81 centimeters) in length, making them one of the smallest species of goby fish.

As their name suggests, Red Neon Eviota Gobies are renowned for their vibrant coloration. Their bodies are adorned with a striking red hue, often complemented by a neon blue stripe running along their dorsal fin. This captivating coloration serves as a warning signal to potential predators, communicating their toxicity.

Behavior and Habitat

Red Neon Eviota Gobies are fascinating creatures to observe in their natural habitat. They are typically found inhabiting coral reefs and rocky coastlines, where they seek shelter among crevices and under ledges. These tiny fish are known for their territorial behavior, actively defending their small territories from intruders.

Red Neon Eviota Gobies are also known for their unique feeding habits. They primarily consume small crustaceans, such as copepods and amphipods, which they capture using their specialized mouths. These fish are opportunistic feeders, often darting out from their hiding spots to snatch prey that passes by.

Care and Maintenance

If you’re considering adding a Red Neon Eviota Goby to your marine aquarium, there are a few essential factors to keep in mind to ensure their well-being.

  • Tank Size: Red Neon Eviota Gobies are small fish, but they still require adequate space to swim and explore. A tank size of at least 10 gallons is recommended for a single fish, with additional space required for multiple individuals.
  • Water Parameters: Red Neon Eviota Gobies thrive in saltwater aquariums with stable water parameters. The ideal water temperature range is between 72°F and 78°F (22°C to 26°C), with a pH level between 8.1 and 8.4. Regular water changes are essential to maintain water quality and prevent the buildup of harmful toxins.
  • Diet: Red Neon Eviota Gobies are carnivorous fish and require a diet consisting primarily of live or frozen foods, such as brine shrimp, mysis shrimp, and copepods. It’s important to provide a varied diet to ensure they receive all the necessary nutrients.
  • Tank Mates: Red Neon Eviota Gobies are generally peaceful fish, but they can be territorial towards their own species. It’s best to keep a single individual or a small group of compatible tank mates, such as other small, peaceful fish or invertebrates.


Breeding Red Neon Eviota Gobies in captivity is a challenging task, but it can be rewarding for experienced aquarists. These fish are known to form monogamous pairs during the breeding season, and they exhibit elaborate courtship rituals. Once the eggs are laid, the male will guard them until they hatch.


The Red Neon Eviota Goby is a captivating and unique fish that can add a touch of color and intrigue to any marine aquarium. With proper care and maintenance, these tiny creatures can thrive and bring joy to aquarists for years to come.
