Firefish Goby Care Guide: The Perfect Nano Reef Fish

<p>The <strong>Firefish Goby</strong> (<em>Nemateleotris magnifica</em>) is one of the best beginner-friendly reef fish available — peaceful, hardy, small, and 100% coral safe. Here is everything you need to keep one healthy.</p>

<h2>Firefish Goby quick facts</h2> <ul> <li><strong>Max size:</strong> 3 inches</li> <li><strong>Minimum tank:</strong> 20 gallons</li> <li><strong>Reef safe:</strong> Yes — 100%</li> <li><strong>Temperament:</strong> Peaceful, shy</li> <li><strong>Diet:</strong> Carnivore — mysis, brine, small pellets</li> </ul>

<h2>Setup and tankmates</h2> <p>Firefish are jumpers — a tight-fitting lid or mesh screen is mandatory. Provide plenty of rockwork with caves; they retreat instantly when startled. Best housed with equally peaceful tankmates: clownfish, small gobies, cardinalfish, and dwarf wrasses. Avoid dottybacks, hawkfish, and aggressive damsels.</p>

<h2>Single, pair, or group?</h2> <p>Single Firefish do great alone. Pairs work if introduced simultaneously as juveniles in a 40+ gallon. Groups of 3+ require 75+ gallons and careful introduction to avoid dominance fights.</p>

<h2>Feeding</h2> <p>Offer small carnivore foods twice daily: frozen mysis, enriched brine, PE calanus, and 1mm pellets. They are picky the first week — persistence and live brine can jump-start feeding.</p>

<h2>Common problems</h2> <ul> <li><strong>Jumping:</strong> The #1 killer. Cover every gap in the lid.</li> <li><strong>Bullying:</strong> Firefish are near the bottom of the pecking order. Add them <em>first</em>, before any semi-aggressive fish.</li> <li><strong>Hiding:</strong> Normal for 3–7 days. If still hiding after 2 weeks, check water quality and tankmates.</li> </ul>
