Overview

The Neon Tetra (Paracheirodon innesi) is a Freshwater (Tropical) fish growing to about 1.5 in and living 5–8 yrs. It's peaceful and best kept in a school of its own kind. Plan a tank of at least 10–20 gal. With a typical lifespan of around 7 years, it's a shorter commitment.

Is the Neon Tetra right for you?

A good match if — you're new to fishkeeping and want a hardy species; you like the look of a moving shoal and can keep a group; you want a calm community tank.

Think twice if — you only want a single fish.

What a Neon Tetra needs from you

The ongoing work is water quality: filtration, regular water changes and stable parameters. As a tropical fish it needs a stable, heated tank. This is a schooling fish — keep a group, never a lone individual. Don't undersize the tank (minimum about 10–20 gal).
