Fahaka Puffer
Tetraodon lineatus
The Fahaka Puffer (Tetraodon lineatus) is an aggressive fish that's best left to experienced keepers. Give it a tank of at least 500 litres (132 US gallons), water held at 75-82°F, and a pH of 7-8.
Captive lifespan reflects typical experience in a home aquarium, not maximum recorded age; genetics, sourcing, and care vary.

Fahaka Puffer Tank Setup
Give them at least 500 litres (132 US gallons) - many puffers are messy and can deliver a real bite. Keep the water at 75-82°F with a pH around 7-8; a species-only tank is often the safest choice. They grow to around 43 cm, so plan the tank size and filtration for a full-grown adult rather than the small juvenile you see in the shop.
What Do Fahaka Puffers Eat?
They're meat-eaters, so feed good-quality frozen or gel foods rather than relying on generic flake. Go easy on portions - leftover protein fouls the water faster than plant foods do.
Fahaka Puffer Tank Mates
MUST be kept as a solitary specimen - will attack and kill all tankmates including fish much larger than itself. Grows to 43cm and requires 500L+ as an adult. Beak-like teeth grow continuously and must be worn down with hard-shelled foods (snails, mussels). Can bite handlers during maintenance. The Fahaka Puffer is aggressive, which is the first thing to weigh up when you choose tank mates. It's a known fin-nipper, so avoid bettas, guppies, and other slow, long-finned fish. It's predatory, so anything small enough to fit in its mouth will be treated as food rather than a companion. Before you buy, run your full stocking list through our stocking calculator. It weighs temperament, adult size, and water needs together, which a single species page can't do on its own.
Are Fahaka Puffers Good for Beginners?
Not a sensible first purchase. Get the tank cycled, keep easier fish stable for a year, then revisit if you still want the extra work this species demands.
Fahaka Puffer - frequently asked questions
What size tank do Fahaka Puffers need?
Fahaka Puffers need a tank of at least 500 litres (132 US gallons). A bigger tank is always easier to keep stable, and gives them more room to settle in and behave naturally.
What water parameters do Fahaka Puffers need?
Keep them at 75-82°F with a pH of 7-8, steady rather than chased to an exact figure. In a cycled tank, ammonia and nitrite should both read 0 ppm, with nitrate kept low through regular water changes.
What do Fahaka Puffers eat?
Fahaka Puffers are meat-eaters. Feed good-quality frozen or gel foods rather than relying on generic flake, and don't overfeed. Feed small amounts once or twice a day, and remove anything they don't eat.
Are Fahaka Puffers good for beginners?
Fahaka Puffers are not a beginner species. They need precise conditions and consistent maintenance, so build experience with hardier fish before keeping them.
Common mistakes with Fahaka Puffers
- Underestimating tank size - the minimum footprint is 500 litres (132 US gallons); impulse buying into a smaller tank leads to stress and shortened lifespan.
- Adding to a new tank - Fahaka Puffers need a fully cycled, stable aquarium; ammonia spikes in new setups are usually fatal.
- Mixing with long-finned fish - Fahaka Puffers will nip at bettas, angelfish, and other fish with flowing fins, causing stress and infection risk.

Great tank mates
Chosen from temperament, overlapping temperature/pH bands, plausible minimum tank footprints, and size versus yours in App-aquatic data. Hobby nuance always wins - verify stocking and temperament before purchasing.
