3. Setting Up the Right Habitat for Minnows

Creating the right habitat is crucial for the health and happiness of your minnows. They need an environment that mimics their natural surroundings.

3.1. Tank Size and Requirements

Tank Size: A 10-gallon tank is suitable for a small group of minnows (6-8 fish). For larger groups, consider a 20-gallon or larger tank.
Material: Use a glass or acrylic aquarium.
