The Stinging Catfish, scientifically known as Heteropneustes fossilis, belongs to the family Heteropneustidae. A distinctive feature of this catfish is its incredible adaptability, which is evident in the structure of its swim bladder. It has evolved into an air sac connected to the gill chamber, functioning as a type of lung. Thanks to this adaptation, the fish can breathe atmospheric air and survive out of water for extended periods. To prevent desiccation, the catfish produces a specific mucus.

Frequently asked questions

The essentials: size, tank volume, water parameters and care

How big does Stinging Catfish get?

An adult reaches 30 cm in length. Plan the tank around the maximum size: the fish quickly outgrows a cramped setup.

What size aquarium does Stinging Catfish need?

The minimum recommended volume is 250 L. A smaller tank speeds up nitrate build-up and raises stress levels.

What water parameters does Stinging Catfish need?

Temperature 20–25 °C, pH 6–8, hardness 5–20 dGH. Stability matters more than exact values: sudden swings are harder on the fish than a small deviation from the ideal.

How long does Stinging Catfish live?

Around 15 years when kept properly. Lifespan depends directly on tank volume, water quality and a varied diet.

Is Stinging Catfish aggressive?

Temperament: semi-peaceful (dangerous to smaller ones). Keep this in mind when choosing tank mates.

How many Stinging Catfish should be kept together?

Recommended setup: small group (3–4 individuals). Ignoring this is a common cause of stress and disease.

What does Stinging Catfish eat?

Diet type: any (universal). Feed small portions that are finished within a couple of minutes — overfeeding does more harm than underfeeding.

What is the scientific name of Stinging Catfish?

The scientific name of the species is Heteropneustes fossilis, family Heteropneustidae. It also appears in the literature as: Saccobranchus fossilis, Saccobranchus microcephalus, Saccobranchus singio.
