Neon Tetra
description Neon Tetra Overview
Neon Tetras are arguably the quintessential beginner fish. These tiny, vibrant fish (around 1.5 inches) thrive in schools of 6 or more, creating a stunning visual display. They are incredibly peaceful and compatible with almost any other community fish. They prefer slightly acidic water and temperatures between 72-78°F.
Neon Tetras are omnivores, readily accepting flake food, but benefit from occasional live or frozen treats. Their sensitivity to water quality changes makes them a good indicator of a healthy tank, prompting beginners to learn proper maintenance.
