大鳞裂峡魮 · Hampala Barb

Overview

A powerful open-water predator, Hampala macrolepidota is unsuitable for ordinary domestic aquariums. Its role as a food and sport fish better reflects its eventual scale than the small juveniles sometimes offered in shops.

Distribution & habitat

The broad range extends through Myanmar, Thailand, and the Mekong region, then south to the Malay Peninsula and the major Sunda islands. Stocking has contributed to its occurrence in some waters. Clear, oxygenated rivers are favored, although lakes and reservoirs are also occupied.

Large fish reportedly frequent deep main-channel pools, often around submerged timber. Seasonal floods provide access to forested feeding and spawning areas.

Aquarium setup

Only public exhibits or exceptionally large private installations are appropriate. Preserve expansive clear swimming space, using gravel, boulders, and wood sparingly. Excellent filtration, oxygenation, and circulation are essential because accumulated organic waste is poorly tolerated. A heavy secure cover is necessary for a fish capable of a forceful escape jump.

Diet & feeding

Wild prey includes smaller fish, insects, and freshwater crustaceans. Plant remains may arrive indirectly inside prey. Match food size to growth: bloodworms and chopped shrimp suit youngsters, while adults take larger worms, mussels, whole shrimp, and suitable small food fish. Dried preparations can be included without becoming the entire diet.

Portion control matters with this enthusiastic feeder. Avoid heavy use of mammalian or poultry meat, and do not rely on live feeder fish that can introduce parasites and disease.

Behaviour & compatibility

It sucks prey into the mouth and is otherwise relatively peaceful toward fish it cannot swallow. Size, speed, and feeding dominance still exclude timid or slow companions. Use robust partners of comparable dimensions. Five or more individuals distribute hierarchical pressure better than two or three; solitary fish may behave nervously.

Sexual dimorphism

A mature female is likely to be more heavily built than a male.

Breeding

Wild spawning accompanies rainy-season movement into flooded forest. Confirmed aquarium breeding remains unrecorded.

Notes

The main dark band starts ahead of the dorsal fin, and both tail lobes have black marginal lines. Juvenile similarities and fading markings in very large adults complicate identification.
