Mystus tengara is a catfish of the family Bagridae. It originates from South Asia and inhabits river systems in Pakistan, India, Nepal, and Bangladesh.
In the wild, adults can reach up to 18 cm in length. In the aquarium, however, they usually remain much smaller, typically growing only to about 10 cm. The mystus tengara has an elongated, slender body with a slight hump on the back, which supports a tall dorsal fin. Its large fins and forked tail indicate an active lifestyle. The body is silver with a green and yellow sheen, marked by rows of dark horizontal stripes running from head to tail. It is nearly identical in appearance to its close relative, the striped mystus, and to most aquarists the two species look the same both in appearance and in their care requirements. Because of this, many suppliers do not always distinguish between them accurately and may use either name for both species.
Mystus tengara is widespread throughout South Asia, including waters in Pakistan, India, Bangladesh, Nepal, Myanmar, and Afghanistan. In nature it inhabits various freshwater biotopes, ranging from still waters to flowing rivers in lowland and foothill areas.
This species has a peaceful and calm temperament. These catfish prefer to stay in groups, so it is recommended to keep at least 3–4 individuals together. They get along well with many other peaceful fish of comparable size.
For a small group, the minimum aquarium volume should be from 250 litres. Provide dense aquatic plants, driftwood, and other natural or artificial elements as hiding places. Mystus tengara prefers soft, slightly acidic water. Aim for little to no water flow. Choose a filter that does not create excessive water movement.
This is an omnivorous species that readily accepts most common prepared foods for aquarium fish.
Breeding in the aquarium is difficult and typically requires pituitary injections to stimulate spawning. Spawning is either in pairs or groups, occurring at night in tanks of at least 200 litres with a substrate of fine-leaved plants or artificial spawning mops. The eggs develop for about 30 hours, after which the larvae hatch and begin feeding on live dust and brine shrimp nauplii a few days later.
No specific species diseases have been documented. However, like most catfish, they are sensitive to water quality and salt content. Maintain stable water conditions and effective filtration to prevent bacterial infections of skin and fins, which can develop under poor sanitary conditions.
When selecting individuals, check for intact fins and the absence of spots or ulcers on the body, as these fish can show intraspecific aggression. Healthy catfish should be active in the evening and have clear, transparent eyes. Be aware that mystus tengara has sharp spines in its fins, so handle it with care during transport and transfer.

Matching water does not mean the plant will stay intact.
The essentials: size, tank volume, water parameters and care
An adult reaches 8–10 cm in length. Plan the tank around the maximum size: the fish quickly outgrows a cramped setup.
The recommended volume is 250 L. A smaller tank speeds up nitrate build-up and raises stress levels.
Temperature 20–27 °C, pH 6–7, hardness 5–15 dGH. Stability matters more than exact values: sudden swings are harder on the fish than a small deviation from the ideal.
Around 5 years when kept properly. Lifespan depends directly on tank volume, water quality and a varied diet.
Temperament: peaceful (regular). Keep this in mind when choosing tank mates.
Recommended setup: small group (3–4 individuals). Ignoring this is a common cause of stress and disease.
Diet type: sinking (any). Feed small portions that are finished within a couple of minutes — overfeeding does more harm than underfeeding.
The scientific name of the species is Mystus tengara, family Bagridae (naked catfishes). It also appears in the literature as: Macrones tengara, Mystus tengana, Mystus tengra.
