虎皮鱼 · Tiger Barb

Overview

Puntigrus tetrazona, the tiger barb, is a lively shoaling fish with conspicuous vertical markings. Farmed ornamental forms dominate aquarium sales. The precise identity of some commercial tiger-barb stock remains confused, so a trade label alone does not resolve taxonomy.

Distribution & habitat

The species is probably native only to central and southern Sumatra, Indonesia. Some older Bornean records concern related species. Its own habitat preferences remain unconfirmed; clear forest streams used by relatives should not be presented as established habitat for this species.

Aquarium setup

Plants, floating cover, and branching wood can improve shelter and display without requiring a particular decorative style. Allow ample room for the group, since restricted space can worsen social problems. Commercial strains tend to be adaptable, while wild stock is better suited to softer water with an acidic to neutral reaction.

Diet & feeding

The suspected wild menu emphasizes aquatic invertebrates, with smaller contributions from plants and organic debris. Feed varied prepared products, including some with plant ingredients, alongside regular small live or frozen prey.

Behaviour & compatibility

Fin damage to tankmates is a recognized risk, especially in cramped tanks or undersized groups. Start with at least eight to ten tiger barbs so that much of their activity is directed toward one another. Males compete within a loose social hierarchy.

Avoid timid, slow, or flowing-finned companions. Robust fish of comparable size, together with suitable bottom-dwelling loaches, offer more promising possibilities after their needs have been checked.

Sexual dimorphism

Mature males are generally leaner, smaller, and more intensely colored than females.

Breeding

Egg scattering occurs without parental care. Occasional fry may survive in an established aquarium, but a separate spawning tank improves control. Fine plants, mops, or mesh can keep eggs beyond adult reach. Provide subdued light and gentle aeration.

Conditioned pairs or groups may be used. Remove adults after spawning. Hatching usually occurs within 24–48 hours, with independent swimming approximately a day later. Start fry on microscopic foods, then introduce microworms and brine shrimp nauplii as their mouths grow.

Notes

Albino, green, and golden selections share the same basic husbandry. Excessive inbreeding can produce weak or malformed fish. Artificial color injection has also been reported, making stock quality more important than unusually vivid coloration.
