29 Gallon is a 76.2 × 30.5 × 45.7 cm (30 × 12 × 18 in) aquarium, rated at 110 L (29 gal). Its footprint is 76.2 × 30.5 cm and the water stands about 39.7 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
- 29 Gallon is 76.2 × 30.5 × 45.7 cm (30 × 12 × 18 in) — rated at 110 L (29 gal), and roughly 85 L (22 gal) of actual water once a 6 cm substrate layer and the hardscape are in.
- That layer takes about 14 L of substrate, which is what you order by.
- 131 of the 160 animals in this library list a minimum tank at or under 110 L (29 gal). The biggest of them that still fit are Pearl Gourami and Congo Tetra. Electric Blue Acara and Angelfish need more than this.
- The water sits about 39.7 cm (15.6 in) deep over the substrate. Plants that get taller than that — Hygrophila corymbosa 'Siamensis' and Water Sprite — reach the surface and start growing along it, which is a look you either want or trim.
- Its footprint is 76.2 × 30.5 cm, and that is the area a carpet has to cover — the number that decides how many pots you buy, not the volume.
