Striped Catfish, Pyjama Cat (Mystus vittatus) — 5-6cm

Overview

The Mystus vittatus, commonly known as the Striped Catfish or Pyjama Cat, is a hardy and visually distinctive freshwater catfish for sale UK. Native to South Asia—including Pakistan, India, Sri Lanka, Nepal, Bangladesh, and possibly Myanmar—this species thrives in slow-moving or still waters with mud substrate and marginal vegetation. Growing to around 5 cm in captivity, it displays bold horizontal stripes and a nocturnal personality that make it a fascinating addition to larger community aquariums. At Tropical Fish Co, we supply healthy juveniles that adapt well to aquarium life and reward attentive care with years of engaging, active behavior.

Appearance and Coloration

Mystus vittatus is instantly recognizable by the bold horizontal black or dark brown stripes that run the length of its silver-cream body, earning it the common name Pyjama Cat. The stripes are crisp and well-defined, creating a striking contrast that persists throughout the fish's life. The body is elongated and slightly compressed, with a broad head, prominent eyes, and long barbels that extend well beyond the head. The fins are semi-translucent with faint banding, and the caudal fin is deeply forked. Juveniles display the same bold patterning as adults, and the stripes remain vivid under subdued lighting.

Natural Habitat and Distribution

This species inhabits slow-moving rivers, lakes, swamps, and brackish water systems with marginal vegetation and mud substrate across South Asia. Water conditions are typically warm (22–28 °C), neutral to slightly acidic, and well-oxygenated. Mystus vittatus is primarily nocturnal, hiding among submerged logs, dense vegetation, and muddy banks during the day. At dusk, it emerges to forage for small invertebrates, worms, and organic debris. During the monsoon season, these catfish move into flooded areas to feed and breed. The natural environment is dimly lit with moderate water flow and abundant hiding places.

Aquarium Setup and Décor

A 60-litre aquarium is suitable for a single Mystus vittatus or a pair. Use soft sand or fine gravel substrate with hiding places such as driftwood, rounded stones, and caves. Live or artificial plants can be used; robust species like Java fern, Anubias, and Vallisneria are preferable. Subdued lighting is essential to reduce stress and encourage natural behavior. A secure lid is mandatory, as this species is a strong swimmer and may jump. Ensure all décor is stable and free of sharp edges. Dim lighting and secure cover help the fish feel confident enough to emerge during feeding times.

Feeding and Nutrition

Mystus vittatus is a carnivore that requires a varied meaty diet. Offer quality sinking carnivore pellets as a staple, supplemented with frozen or live bloodworms, brine shrimp, daphnia, chopped earthworms, and other small invertebrate foods. Some individuals may accept high-quality prepared foods, though meaty options are preferred. Feed once daily in the evening, as this species is primarily nocturnal. Ensure food reaches the substrate and is not consumed entirely by faster mid-water fish. Avoid overfeeding, as uneaten food can degrade water quality.

Behaviour and Social Structure

The Striped Catfish is primarily nocturnal and semi-aggressive. It hides during the day and emerges at dusk to forage. This species can be territorial toward other bottom-dwellers and may prey on very small tankmates. It is best kept singly or with robust fish of similar size. When feeding, it is a confident and assertive eater. Despite its boldness at feeding time, it remains shy and reclusive during daylight hours, only emerging from hiding when the lights are dimmed. Males may display mild territorial posturing, but serious aggression is uncommon in spacious, well-structured tanks.

Compatible Tank Mates

Ideal companions include small to medium peaceful schooling fish of similar size such as danios (zebra, pearl), rasboras (harlequin, scissortail), small barbs (cherry, rosy), and peaceful gouramis of appropriate size. Avoid housing with small fish that can be swallowed, shrimp and other small invertebrates, very slow or long-finned fish, highly aggressive territorial species, or tiny fry and juvenile fish. Fast-moving, mid-water species that will not be harassed or outcompeted are best.

Breeding in the Aquarium

Breeding is uncommon in home aquaria; when successful, it likely requires excellent conditioning with live foods, seasonal water changes, and spacious, well-oxygenated conditions. Specific captive breeding protocols are not well documented. Sexual dimorphism is subtle; females may be slightly larger and plumper when carrying eggs. If breeding is attempted, provide multiple caves and monitor water parameters closely. Spawning may occur after a series of partial water changes that simulate monsoon conditions. Fry, if produced, require specialized care and micro-foods such as infusoria or liquid fry food initially.
