Tank and special needs
Plan for at least 38 litres of water (the care sheet says 10 US gallons).
Nano-friendly.
Corals and invertebrates
None.
Which tankmates suit the neon goby?
Small: keep away from hawkfish, dottybacks and other mouths that fit it.
Suggested order in a mixed tank: add early, with the first peaceful fish.
More than one neon goby
Only as a mated pair, or two juveniles added together. A third neon goby is usually driven out.
Other fish
Checked against the other 59 fish in this guide, assuming a tank big enough for both. Individual fish differ, so treat this as a starting point.

- Carpet anemones (Haddon's, giant)The carpet anemones (Haddon's, giant) can catch and eat small fish such as the neon goby.
These checks follow the reasons fish and invertebrates clash: same species or genus, similar shape, mouth size, temperament, food, burrows, tank size and the order they are added. Individual animals differ; every source agrees on that.
Quarantine and health
Standard quarantine; tiny fish, so keep quarantine tank small and stable.
New fish are the most common way disease gets into a reef tank. Quarantine every fish in a separate tank before it joins the display, and choose a method that suits its tolerance of copper.
Captive-bred or wild?
Commonly captive-bred (ORA, Proaquatix lines listed). Short-lived species, so buy young captive-bred fish.
