Fish & freshwater shrimp collections in preparation.

SPECIES DOSSIER · RESEARCH STAGE

Scleropages formosus

Asian arowana · Osteoglossidae · Piscivore

Identity and native record

Scleropages formosus (Asian arowana) is included because authoritative species records document native occurrence in Sumatra and Kalimantan native populations. “Native to Indonesia” does not imply endemicity, captive availability, legal export, or permission to import.

CITES Appendix I: future trade could only proceed through applicable registered captive-breeding and permit pathways—not ordinary stock listing.

Ecology and adult scale

Feeding guild
Piscivore
Reported adult scale
up to about 90 cm TL
Habitat
Slow rivers, lakes and forest wetlands

Feeding guild is an editorial husbandry aid, not a complete diet prescription. Juvenile and adult diets, seasonal ecology and individual behaviour can differ.

Welfare and suitability screen

Specialist, very large covered system; international movement is governed by strict CITES controls.

Before any future listing, LIMNIC would need to document the individual fish, expected adult dimensions, secure containment, water parameters, diet, compatibility, transport risk and the buyer’s capacity to provide lifetime care.

Evidence and compliance links

  1. CITES Appendices: Scleropages formosus.
  2. Conte-Grand et al. (2017), snakehead taxonomy and identification caution (relevant to Channidae).
  3. IUCN Red List — recheck the accepted taxon and current assessment.
