Identity and native record
Oxyeleotris heterodon (Sentani gudgeon) is included because authoritative species records document native occurrence in Lake Sentani, Papua. “Native to Indonesia” does not imply endemicity, captive availability, legal export, or permission to import.
Native Indonesian occurrence is centred on Lake Sentani; cross-border New Guinea distribution does not imply open trade.

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
Large specialist system; provenance and conservation context must be resolved before any availability.
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.
