Buying Guide

Choose the right tank size

Match gallons to intended livestock—3–5 gal for single bettas or shrimp, 10–20 gal stands for community setups and easier stability

Check glass vs acrylic

Glass resists scratches and stays clearer long-term, while acrylic is lighter and more impact-resistant but scratches easier

Prefer low-iron or rimless for clarity

Low-iron or rimless tanks provide better water and plant color rendering, ideal for planted nano aquariums

Look for included equipment

Tanks with built-in LED lighting and a small power filter simplify startup and reduce initial gear purchases

Account for stand and storage needs

A sturdy stand rated for the tank size and accessible storage for nets, food and maintenance supplies improves safety and convenience
