Overview

October 16, 2026 · Suggest an edit

The zebra acara is endemic to the middle and upper Rio Negro in Brazil and was described in 1993 as Nannacara adoketa. Its silvery-beige body is covered in blue-sheened scales; its thick black vertical bars darken markedly during breeding and while raising fry, and there are orange markings on its face and fins. Males grow to 8–9 cm and develop extended dorsal, anal and pelvic fins; females are about 3 cm smaller. Though it looks cute, its temperament recalls that of Central American cichlids.

Tank Setup

October 16, 2026 · Suggest an edit
  • At least 120 liters for a pair; plenty of decor that breaks lines of sight.
  • 24–27°C, pH 4.5–6.5, very soft water; these values are essential for breeding.
  • Fine sand, roots, dried leaves, flat stones and dim light.

Diet

October 16, 2026 · Suggest an edit

Omnivorous, with a preference for meaty foods. It feeds on frozen bloodworms, brine shrimp, mysis and a quality cichlid granule.

Behavior and Compatibility

October 16, 2026 · Suggest an edit

Aggressive toward its own kind and similar fish; it is best kept in a species tank or only with large, fast companions. It eats small fish and shrimp that fit in its mouth. It spawns on open surfaces; the parents guard the fry together.

Good companions: large, fast tetras and hatchetfish that tolerate soft water (in a large tank).

Avoid: small tetras such as neons and cardinals, other dwarf cichlids, shrimp, slow and shy fish.
