Buying Guide: Key Considerations For 2 Gallon Aquariums
- Tank material and clarity: Clear glass or high-transparency glass helps showcase plants and fish. Look for smooth edges and a sturdy base for desk use.

- Lighting and plants: Adjustable lighting helps coraline algae or live plants thrive, while decorative lighting can enhance viewing aesthetics.
