Blue Tetra

Hints of pink coloration gives the Blue Tetra an iridescent, “blushing” sheen that is brought out to maximum effect in setups with darker substrate. Keep the Blue Tetra in groups of six or more as it is a schooling fish that relishes company.

A planted aquarium of at least 20 gallons or larger will provide an ideal environment for the Blue Tetra. A spacious aquarium aquascaped with live plants, rocks and driftwood replicates its natural habitat and helps reduce stress on this fish. When crowded in an aquarium of inadequate size with too many tank mates, the Blue Tetra may resort to fin nipping. The Blue Tetra does best in soft slightly acidic water with high water quality.

The Blue Tetra will accept many small foods such as Brine Shrimp or Daphnia, freeze-dried Bloodworms and Tubifex, micro pellet food, and a high quality flake food.
