大眼铠甲弓背鱼 · Giant Featherback

Overview

The exceptional adult size of Chitala lopis limits it to public aquariums or the largest specialist facilities. Its traditionally broad range may include several related forms, making identity and provenance uncertain. A juvenile should not be purchased on the assumption that it will remain manageable in an ordinary home tank.

Distribution & habitat

Traditional records cover the Mekong, Chao Phraya, and Mae Klong drainages, Peninsular Malaysia, Sumatra, Borneo, and Java. That complete range requires confirmation.

It is associated primarily with lower river basins and forested tributaries containing complex rock and submerged-wood structure. Some records also come from artificial impoundments.

Aquarium setup

Long-term care requires exceptionally large dedicated accommodation. Keep lighting subdued and provide substantial retreats using wood, rocks, or wide pipes, without compromising maneuvering space.

Very large mature filtration, highly oxygenated water, and some current are necessary. Weekly partial changes of approximately 50–70% underline the maintenance commitment. Temporary juvenile accommodation is not a substitute for planning the adult installation.

Diet & feeding

This primarily nocturnal carnivorous predator takes smaller fishes, crustaceans, and other invertebrates. Most accept nonliving alternatives. Juveniles can receive bloodworms, small earthworms, and chopped prawn; adults take fish strips, whole shrimp, mussel, and larger worms. Live river shrimp are also accepted.

Pellets may supplement the diet but should not be its sole foundation. Beef heart, chicken, and similar terrestrial meats are unsuitable routine foods. Feeder fish may introduce pathogens or parasites without necessarily providing appropriate nutrition.

Behaviour & compatibility

Experience with the genus suggests relative tolerance of fishes too large to swallow, alongside possible territorial disputes with conspecifics and similarly shaped species, especially in restricted space. This is a cautious framework for companion selection, not a guarantee that large fishes can safely share accommodation.

Small fishes and shrimp fall within its prey spectrum and are unsuitable companions.

Notes

Older juveniles and adults generally lack the dark body markings seen in related featherbacks and have a more pronounced jaw. Disappearance from Java has been suspected, while the broader identity and range remain unresolved. These uncertainties should not be converted into a confirmed extinction statement or settled taxonomic split.

Members of the family have a long combined anal and caudal fin and can breathe air. Neither feature reduces the requirement for clean, oxygen-rich aquarium water.
