Black arowana

Osteoglossum ferreirai

Silvery-blue adults with dark rear fins and pale orange edging

Adults are not uniformly black; iridescent sides and dark, edged fins mark this form.

A large surface predator and jumper; conspecific territorial behaviour needs attention.

Appearance and identification

Appearance varies. Juvenile coloration is more distinctive; adult silver and black arowanas can be similar.

Provide substantial swimming space.

Eats insects and fish.

Juveniles may be kept together, but adults may not be safe in a group.

Fish small enough to swallow are at risk.
