Golden Puffer (Arothron Meleagris)

Golden Puffer Basics

The Golden Puffer, Arothron meleagris, is a striking saltwater fish. It shows bright gold or spotted patterns. Many hobbyists call it the Guinea Fowl Puffer when spotted. Both forms are the same species.

This fish grows large in captivity. Adults often reach 10–12 inches long. Plan for long-term size before buying one.

Golden Puffers are not reef safe. They nip at corals, inverts, and clams. Keep them in a fish-only or FOWLR system.

Tank Size and Setup

Golden Puffers need room to swim and explore. They also produce heavy waste. A 125-gallon tank is a realistic minimum for juveniles. Larger is better for adults.

Use strong filtration. A quality protein skimmer is almost mandatory. Plan for extra biological media. These fish are messy eaters.

Tank size: 125 gallons or larger
Temperature: 74–78°F (23–26°C)
Salinity: 1.023–1.026 specific gravity
pH: 8.1–8.4

Provide open swimming space in the front. Stack live rock toward the back. Create caves and overhangs. Puffers like to explore and rest in shaded areas.

Use a secure lid. Golden Puffers can startle and jump. Cover any gaps around plumbing.

Feeding the Golden Puffer

Golden Puffers are carnivores with strong beaks. Their teeth grow continuously. They need hard foods to wear them down.

Offer clams on the half shell
Feed unshelled shrimp and crab legs
Use chunks of squid or krill
Rotate frozen marine foods for variety

Feed small portions two times per day. Remove uneaten food after a few minutes. Excess food quickly harms water quality.

Tip: Pre-thaw frozen foods in tank water. This prevents sudden temperature shock.

Temperament and Tank Mates

Golden Puffers are curious and intelligent. They often recognize their owners. Many beg for food at the glass.

Their temperament is semi-aggressive. They may nip slow or long-finned tank mates. Avoid very small fish, shrimp, crabs, and snails. They usually become snacks.

Possible tank mates include:

Large tangs and surgeonfish
Robust wrasses
Triggers with similar temperament
Large angelfish in a big system

Always watch new introductions. Each puffer has its own personality. Be ready to rehome bullied fish.

Health, Care, and Long-Term Commitment

Golden Puffers can live over 10 years with good care. They need stable water parameters. Perform regular water changes and test often.

Puffers are sensitive to poor water quality. Ammonia and nitrite must always be zero. Nitrate should stay low.

These fish do not tolerate copper medications well. Use a separate hospital tank for treatments. Consider alternative medications when possible.

Teeth overgrowth is a common issue. It happens when they lack hard-shelled foods. Prevent this with regular clam and shellfish feedings. In severe cases, a vet or experienced keeper may need to trim the beak.
