125 Gallon
125 Gallon is a 182.9 × 45.7 × 55.9 cm (72 × 18 × 22 in) aquarium, rated at 473 L (125 gal). Its footprint is 182.9 × 45.7 cm and the water stands about 49.9 cm deep once a 6 cm substrate layer is in — the two numbers that decide what you can plant in it and what you can stock it with.

Before it goes in
- 125 Gallon is 182.9 × 45.7 × 55.9 cm (72 × 18 × 22 in) — rated at 473 L (125 gal), and roughly 384 L (101 gal) of actual water once a 6 cm substrate layer and the hardscape are in.
- That layer takes about 50 L of substrate, which is what you order by.
- 154 of the 160 animals in this library list a minimum tank at or under 473 L (125 gal). The biggest of them that still fit are Black Ghost Knifefish and Common Pleco. Oscar and Senegal Bichir need more than this.
- The water sits about 49.9 cm (19.6 in) deep over the substrate. Plants that get taller than that — Hygrophila corymbosa 'Siamensis' and Amazon Sword — reach the surface and start growing along it, which is a look you either want or trim.
- Its footprint is 182.9 × 45.7 cm, and that is the area a carpet has to cover — the number that decides how many pots you buy, not the volume.

How much substrate does it take?
About 50 L for a 6 cm layer.
What fits in it?
154 of the 160 animals in this library list a minimum tank at or under its volume, and the water depth of about 49.9 cm sets which plants can grow without reaching the surface.
What fits in it
- Animals this size will hold: Black Ghost Knifefish, Common Pleco, Chinese Algae Eater, Kissing Gourami and Discus.
