Neon Tetra Tanks – How Many Fish Can Fit?

The average adult neon tetra is about one inch long, so you should be able to fit a maximum of 14 in your tank. Keep in mind that this may not work well with other types of fish because they can outcompete the smaller tetras for food and habitat. Neon Tetras also prefer more space as they are schooling fish, so consider using less in a tank than 14 as your fish will become unhappy.

In order to make sure neon tetras are happy, it is important that you understand their requirements. For small fish like the Neon Tetra, they need about 1 gallon of water for a fish that grows up to around 2″. This means if your tank has 3-4 gallons per inch in width (or 18″x18″), then 10 would be enough space for each school with 16 being the maximum number of schools allowed.

Neon tetras are small, schooling fish that require relatively high water quality. They live well in tanks with plenty of hiding spots and carpet plants to provide shade; they also need lots of oxygen, so be sure the filter is running properly and your aquarium has enough surface area for gas exchange.

Ideal Number of Neon Tetras For a 10 Gallon Tank

If you want your fish to be able to swim around, there’s a strict guideline for the number of tetras in tanks. For example, 10 gallons should only contain 5-6 tetras; this is why it’s considered best for small groups rather than cramped spaces. Of course, if they’re smaller they could have up to 6-8 per tank as long as all guidelines are followed and everything runs smoothly!
