Chitala lopis (Bornean Knifefish, Giant Featherback Knifefish)

Chitala spp. featherback knifefish are non-electric knifefishes found in swampy and riverine environments across South and Southeast Asia. They are big fish, and their major economic value is as food fish rather than aquarium fish. As such, these are animals for jumbo tanks 400 l/100 gal in size.

Body colour is plain grey when young, becoming silvery as the fish matures.


Fish information (behaviour and breeding):

Featherback knifefish supposedly form groups in the wild, but they are territorial and aggressive under aquarium conditions. Juveniles will usually tolerate tankmates fairly well, but as they mature they become increasingly short tempered, and given their size and considerable strength. Sometimes kept successfully with large and robust tankmates including pacu, thorny catfish, arowana, tinfoil barbs, etc.

Predatory; will consume small fish. Prefers live foods such as earthworms and river shrimps. Feeder fish are not necessary; once settled this fish will eat a variety of frozen foods including shrimps, whitebait and other items of seafood.

Featherback knifefish are bred on fish fish farms, but there are no reports of breeding in home aquaria.
