Overview

October 16, 2026 · Suggest an edit

The jellybean tetra is an Alestidae species about 3.5 cm long that comes from small streams in the coastal forests of West Africa. A thin line that shines in the light runs along its semi-transparent amber body; its fins are orange-red. It is rarely found in the trade. Because of its shy nature, it should be kept in a calm, planted, dimly lit aquarium.

Tank Setup

October 16, 2026 · Suggest an edit
  • At least 40 liters for a group of 8–12.
  • 23–26°C, pH 5.5–7, soft water.
  • Dense plants, roots, leaf litter and dim light.
  • It is an excellent jumper; a tight lid is essential.

Diet

October 16, 2026 · Suggest an edit

Omnivorous, but its mouth is small. Micro granules, fine flakes, frozen cyclops, daphnia and newly hatched brine shrimp are suitable. Feed small amounts 1–2 times a day.

Behavior and Compatibility

October 16, 2026 · Suggest an edit

Peaceful and shy. It comes out into the open more in a large group and with calm tankmates; when kept in small numbers it hides among the plants. It does not harm shrimp.

Good companions: small tetras, micro rasboras, pencilfish, pygmy corydoras, dwarf shrimp.

Avoid: active and large species, greedy competitors for food, predators.
