Before it goes in
- Juwel Rio 125 is 81 × 36 × 50 cm (31.9 × 14.2 × 19.7 in) — rated at 125 L (33 gal), and roughly 118 L (31 gal) of actual water once a 6 cm substrate layer and the hardscape are in.
- That layer takes about 17 L of substrate, which is what you order by.
- 131 of the 160 animals in this library list a minimum tank at or under 125 L (33 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 44 cm (17.3 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 81 × 36 cm, and that is the area a carpet has to cover — the number that decides how many pots you buy, not the volume.
