180P (171 gallon)
180P is a 180 × 60 × 60 cm (70.9 × 23.6 × 23.6 in) aquarium, about 648 L (171 gal) to the rim. Its footprint is 180 × 60 cm and the water stands about 54 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
- 180P is 180 × 60 × 60 cm (70.9 × 23.6 × 23.6 in) — about 648 L (171 gal) to the rim, and roughly 537 L (142 gal) of actual water once a 6 cm substrate layer and the hardscape are in.
- That layer takes about 65 L of substrate, which is what you order by.
- 157 of the 160 animals in this library list a minimum tank at or under 648 L (171 gal). The biggest of them that still fit are Clown Loach and Oscar. Tinfoil Barb and Bala Shark need more than this.
- The water sits about 54 cm (21.3 in) deep over the substrate. Plants that get taller than that — Hygrophila corymbosa 'Siamensis' and Cabomba — reach the surface and start growing along it, which is a look you either want or trim.
- Its footprint is 180 × 60 cm, and that is the area a carpet has to cover — the number that decides how many pots you buy, not the volume.
What are its dimensions?
180 × 60 × 60 cm (70.9 × 23.6 × 23.6 in).
How much water does it hold?
About 648 L (171 gal) to the rim, and roughly 537 L (142 gal) of actual water once the substrate is in. Stocking works off the second number; minimum-tank-size advice works off the first.
How much substrate does it take?
About 65 L for a 6 cm layer.
What fits in it?
157 of the 160 animals in this library list a minimum tank at or under its volume, and the water depth of about 54 cm sets which plants can grow without reaching the surface.
What fits in it
- Animals this size will hold: Clown Loach, Oscar, Senegal Bichir, Black Ghost Knifefish and Common Pleco.
- Plants that stay under its water line: Water Sprite, Anubias nana 'Petite', Cryptocoryne wendtii and Dwarf Hairgrass Mini.
