90P (48 gallon)

90P is a 90 × 45 × 45 cm (35.4 × 17.7 × 17.7 in) aquarium, about 182 L (48 gal) to the rim. Its footprint is 90 × 45 cm and the water stands about 39 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

  • 90P is 90 × 45 × 45 cm (35.4 × 17.7 × 17.7 in) — about 182 L (48 gal) to the rim, and roughly 145 L (38 gal) of actual water once a 6 cm substrate layer and the hardscape are in.
  • That layer takes about 24 L of substrate, which is what you order by.
  • 136 of the 160 animals in this library list a minimum tank at or under 182 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 39 cm (15.4 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 90 × 45 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?

90 × 45 × 45 cm (35.4 × 17.7 × 17.7 in).

How much water does it hold?

About 182 L (48 gal) to the rim, and roughly 145 L (38 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 24 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 39 cm sets which plants can grow without reaching the surface.
