The Swell Premium 50cm Tropical Fish Tank sits sixth in this guide. It is a rectangular 38-litre aquarium measuring 50 x 26 x 32 cm, sold at £83.99 with dual-mode LED lighting (daylight and moonlight settings) and a 4-stage filtration system. The listing rates it 4.4 out of 5 from 19 ratings.

That price is worth putting beside the guide's £99.99 group. Three other tanks in this set cost £99.99 and hold 20, 34 and 54 litres — so the Swell asks £16 less than all three of them, and still offers 4 litres more water than the 34-litre one at that higher price. The second oddity is in the ratings themselves: the page states 19 ratings, while the star breakdown runs 72 five-star, 12 four-star, 8 three-star and 8 one-star, which adds up to 100. Both figures sit on the same listing. Everything below is taken from that Amazon listing, not from any tank we tested ourselves.
