Before it goes in

  • Juwel Rio 180 is 101 × 41 × 50 cm (39.8 × 16.1 × 19.7 in) — rated at 180 L (48 gal), and roughly 168 L (44 gal) of actual water once a 6 cm substrate layer and the hardscape are in.
  • That layer takes about 25 L of substrate, which is what you order by.
  • 136 of the 160 animals in this library list a minimum tank at or under 180 L (48 gal). The biggest of them that still fit are Electric Yellow Lab and Peacock Eel. Siamese Algae Eater and Boesemani Rainbowfish 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 101 × 41 cm, and that is the area a carpet has to cover — the number that decides how many pots you buy, not the volume.

About 25 L for a 6 cm layer.

What fits in it?

136 of the 160 animals in this library list a minimum tank at or under its volume, and the water depth of about 44 cm sets which plants can grow without reaching the surface.
