The Neon Tetra is an eye-catching fish that looks great in any aquarium! It’s a popular choice among aquarium hobbyists for its vibrant colors and peaceful demeanor. If you’re thinking about adding a Neon Tetra to your tank setup, here’s everything you need to know about taking care of this unique fish. 

Tank Setup & Size Requirements 

Neon Tetras are shoaling fish, so they should always be kept in groups of at least four or more. A 20-gallon (around 90 liters) tank is large enough for a school of six to eight tetras. Make sure to include plenty of plants and hiding places, as well as rocks, driftwood, and other decorations. As long as the tank is well maintained with a temperature for your neon tetra between 72°F and 80°F (22-27 Celsius), the Neon Tetra will thrive in most tanks. 

What Does a Neon Tetra Eat?

In the wild, Neon Tetras feed on small insects, larvae and other types of invertebrates. In captivity, neon tetras will eat almost any type of food including flake food, frozen food such as brine shrimp or bloodworms, and live foods such as daphnia or white worms. Feed your tetras two or three times per day with only what they can consume within two minutes; any excess should be scooped out immediately after feeding time ends, to avoid water contamination.

Tank Mates & Plants 

The neon tetra is quite peaceful by nature and makes an excellent addition to community tanks with similarly sized non-aggressive species like Danios, Corydoras catfish, guppies and other small tropical fish. Avoid larger aggressive species like Oscars – these can easily prey on the much smaller neon tetras! As for plants – Java Ferns are ideal since they are slow growing but hardy enough to survive in most water conditions; other good options include Anubias Nana and Cryptocoryne if you want something that requires less maintenance. 


The Neon Tetra is one of the most popular aquarium fish available today thanks to its striking coloration and peaceful nature. With proper care and maintenance it can live several years in your aquarium. To ensure your new school of tetras thrive for years to come make sure their tank has plenty of hiding spots and plants for them to explore while also providing them with a varied diet featuring both fresh, frozen and dried foods as well as an appropriate number of tank mates that won’t harass them too much (avoid larger aggressive fish). Follow these tips and you’ll have happy healthy neon tetras in no time!
