Glass Aquarium vs. Acrylic Aquarium
Compare glass and acrylic aquariums by weight, scratch resistance, clarity, cost, and support needs.
Who this guide is for
This comparison is for choosing a tank material before buying a new aquarium or upgrading to a larger setup.
What to compare
Glass is scratch resistant and common. Acrylic is lighter and can be clearer, but it scratches more easily. Large tanks need careful stand and floor planning either way.
Buying guidance
Estimate filled weight before choosing a stand. The tank material changes empty weight, but water, substrate, and decor are still the largest load.
