At a glance the quick version
Looks how to spot one
Small torpedo-shaped goby
A slim, torpedo-shaped little goby with a dark back and a glowing electric-blue stripe running from snout to tail, set off by a pale stripe in front of each eye.12
Personality what they are like
Peaceful and busy. It sets up a cleaning station and invites other fish over to be groomed, and it lives happily in a bonded male and female pair.123
Daily activity how busy a day looks
An active perching fish that zig-zags near its station on rocks or coral heads to advertise its cleaning service.21
Grooming and care the hands-on bits
Described as extremely hardy and suitable for beginners. Keep water stable and clean, and acclimate slowly over a few hours. Avoid large predatory tank mates.32
Home where they are happiest
A reef aquarium from about 40 litres (10 US gallons), or around 75 litres (20 US gallons) for spawning pairs, with live rock for perching. Suggested water: 22 to 26 C (72 to 78 F), pH 8.1 to 8.4. Reef, coral and invertebrate safe.31
Food basics what goes in the bowl
A carnivore that picks parasites off other fish in the wild and also takes copepods and zooplankton. In the aquarium offer small meaty foods such as mysis, copepods and small pellets or flakes.213
Company who they like around
Socially monogamous; pairs stay together at their cleaning station. Keep singly or as a pair.12
The story where it all began
The neon goby was described by the American ichthyologist David Starr Jordan in 1904. It is the best-known of the Caribbean cleaning gobies and has been bred successfully in captivity, which makes captive-raised fish easy to find.12
Fun facts for the dinner table
- 1
Neon gobies run cleaning stations on coral heads, removing parasites from the skin, fins, mouths and even gill chambers of much bigger fish such as groupers.1
- 2
To attract customers they perform a zig-zag swimming dance in front of their station.2
- 3
Their bright blue stripe acts as a signal that says 'cleaner, not food', helping them work safely around predators.2
- 4
After hatching, the larvae drift for about 30 days before they settle and turn into juveniles.2

Owner questions the things everyone asks

Feed small amounts once or twice a day. Furry Diary's starting plan is to feed daily, offering just enough that your goby eats in a couple of minutes.2 Furry Diary plan
What does a Neon Goby eat, and what should it never eat?
It eats small meaty foods like mysis, copepods, and small pellets or flakes. Never feed large or plant-based foods, as it is a carnivore.213
How much space does a Neon Goby need?
A single or pair needs at least 40 litres (10 US gallons), with 75 litres (20 US gallons) recommended for spawning pairs. Provide live rock for perching.31
What temperature, light or water does a Neon Goby need?
Keep water at 22 to 26°C (72 to 78°F) with a pH of 8.1 to 8.4. It is reef-safe and needs stable, clean saltwater with slow acclimation.31
How often should I clean a Neon Goby's home?
Furry Diary's plan suggests a weekly glass clean and a 10-20% water change every two weeks. Test water weekly and top up evaporation daily with fresh RO water. Furry Diary plan
Can a Neon Goby live with others?
Yes, it is peaceful and can live with other non-predatory fish. It is socially monogamous, so keep it singly or as a bonded pair.12
How long does a Neon Goby live?
Lifespan varies with care; ask your vet or a good breeder for typical expectations in a home aquarium.
Can I handle a Neon Goby?
It is best not to handle this fish, as it is delicate and easily stressed. Enjoy watching its busy cleaning station behavior instead.21
