Caring for a Neon Tetra

Posted by Team ADI on

Neon tetra are small fish native to southeastern Colombia, eastern Peru, and Western Brazil.  Their bright coloring makes them a popular fish among aquarium hobbyists and are relatively easy to care for.  Here are some pointers on caring for your neon tetra:

1. Keep the water temperature around 21–27 °C (70–81 °F).  This temperature best resembles their native Amazon environments.

2. Neon Tetra are omnivores and will also eat algae, small invertebrates, and insect larvae.  They are not picky and should be fed a variation of commercial and live food.

3. They should be stocked with other non-aggressive species, as larger, more aggressive fish will bully or eat them.  Many aquarists will stock them with other small, non aggressive fish.  They are often stocked with groups of six or more neon tetras, as hobbyists will be able to witness the shoaling effect when they swim around the tank.

4. Aquariums stocked with neon tetras should be decorated with many plants.  They are native to the Amazon, and tetras thrive when there are many plants around.

5. If your neon tetra is restless or has a dull color for multiple days in a row, it could have Neon Tetra Disease.  There is no known cure for this disease, and is often fatal if they catch it.  If you suspect one of your neon tetras is showing symptoms, quarantine him because the disease could spread to other neon tetras in your aquarium.

Enjoy these colorful fish in your aquarium!
