Appearance and identification

Indonesian tiger perch may be mis-sold under this name. Fewer broad bars and warmer colour are useful clues, but stripes alone do not identify it.

Adult space

Plan public-display or exceptionally large private accommodation, stable water and careful feeding observation after arrival.

Diet and feeding

Offer suitable aquatic animal foods; mammalian meat or random feeder fish is not a complete feeding plan.

Same-species behaviour

Adults are not reliably schooling; no group number guarantees harmony.

Compatibility limits

Small fish and shrimp remain prey.

Aquarium environment

Floating cover does not replace space or filtration.
