Jaguar Catfish
Siluriformes sp.
The Jaguar Catfish (Siluriformes sp.) is a peaceful bottom-dweller fish that's easy to keep. Give it a tank of at least 245 litres (65 US gallons), water held at 72-82°F, and a pH of 6-7.8.
Captive lifespan reflects typical experience in a home aquarium, not maximum recorded age; genetics, sourcing, and care vary.

Jaguar Catfish Tank Setup
Plan for at least 245 litres (65 US gallons) with soft sand or smooth, rounded gravel - sharp substrate wears down their delicate barbels. Keep the water at 72-82°F with a pH around 6-7.8. They reach about 23 cm as adults, so don't be misled by the small juveniles sold in stores.
What Do Jaguar Catfish Eat?
They're bottom feeders, so give them sinking wafers, tablets, or frozen treats like bloodworm once the lights go down. Flakes that never reach the bottom leave them hungry even when the tank looks well-fed.
Jaguar Catfish Tank Mates
Requires a large tank and good filtration. The Jaguar Catfish is peaceful bottom-dweller, which is the first thing to weigh up when you choose tank mates. At around 23 cm fully grown, it needs tank mates that can hold their own against its size and appetite. 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 Jaguar Catfish Good for Beginners?
Reasonable early choice after cycling. Buy after the tank has stable ammonia and nitrite readings, not the same weekend you fill it.
Jaguar Catfish - frequently asked questions
What size tank do Jaguar Catfish need?
Jaguar Catfish need a tank of at least 245 litres (65 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 Jaguar Catfish need?
Keep them at 72-82°F with a pH of 6-7.8, 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 Jaguar Catfish eat?
Jaguar Catfish are bottom feeders. Give them sinking wafers, tablets, and frozen foods that settle on the substrate, ideally after the lights go off. Feed small amounts once or twice a day, and remove anything they don't eat.
Are Jaguar Catfish good for beginners?
Yes - Jaguar Catfish are a reasonable beginner fish once the tank is cycled and parameters are stable. Add them after ammonia and nitrite read 0 ppm, not the same day you fill the tank.
Common mistakes with Jaguar Catfish
- Underestimating tank size - the minimum footprint is 245 litres (65 US gallons); impulse buying into a smaller tank leads to stress and shortened lifespan.

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.
