Blue King Tetra

A lively blue tetra sold under the Blue King trade name. Its reflective blue coloration adds movement to a community aquarium, especially when kept in a good-sized group.

Aquarium and care

Provide a mature tropical freshwater aquarium with a generous open swimming area, planted margins, and stable water quality. Keep at least eight together to encourage natural schooling. Blue tetra trade names can cover similar-looking species, so exact identity and adult size should be confirmed when planning a specialized collection.

Feeding

Offer fine quality flakes or small pellets supplemented with small frozen or live foods. Feed modest amounts that the fish can consume promptly.

Temperament and tank mates

Choose active peaceful companions. Crowding or too small a group may encourage chasing or fin nipping; avoid very slow fish with long flowing fins.
