How much do tropical fish cost?

Prices vary by species, size, rarity and current availability. The live product cards show the current price, so use the price filter instead of relying on a static range.

How do I choose tropical fish that can live together?

Compare adult size, temperament, water requirements and group needs. Use the exact product information, reviewed care guides and tank-mate tool before combining species.

Do I need to cycle my aquarium before buying fish?

Yes. Prepare and fully cycle the aquarium before ordering, then confirm that its temperature, water chemistry, size and filtration suit the exact species.

How are tropical fish delivered?

Eligible live-animal orders use specialist delivery and protective packaging. Check the delivery page for the current dispatch schedule, postcode coverage and Live Arrival Guarantee terms.

Is it safe to buy tropical fish online?

Use a specialist seller with clear packaging, delivery, acclimation and Live Arrival Guarantee terms. Prepare the aquarium before dispatch and follow the current arrival instructions.

Choose fish for the aquarium you have

Start with the aquarium, not the colour of the fish. Check its mature water volume, temperature, filtration, pH and hardness, then compare those conditions with the exact product information. Adult size, temperament and social needs matter just as much as the size of a fish when it is offered for sale.

The filters above help narrow the catalogue, but they do not replace a species-specific check. If a product value is missing or uncertain, use the reviewed care guide or ask before ordering rather than assuming that a related fish needs identical conditions.

Start with	Why it matters	What to check
Aquarium volume	Fish need enough mature swimming and territory space	Adult size and minimum aquarium guidance
Water conditions	Species can prefer different temperature, pH and hardness	Your tested water against the exact listing
Temperament	A general “peaceful” label cannot guarantee every pairing	Adult behaviour and a backup plan
Social needs	Some fish need a group while others need their own territory	Species-specific group guidance
Existing livestock	New fish must suit animals already in the aquarium	Adult size, feeding and compatibility

Livebearers including Guppies, Mollies, Platies and Swordtails.
Corydoras, Bristlenose Plecos and other bottom-dwelling fish.
Gouramis and labyrinth fish, Angelfish and cichlid collections for carefully planned centrepiece choices.

The primary grid and count on this page are deliberately fish-only. Browse Shrimps and Crustaceans, Freshwater Snails or Goldfish and Cold-water Fish through their own clearly labelled collections.

Before you order

Confirm that the aquarium is fully cycled and stable for the exact species. Review the current delivery information, prepare for arrival and use the acclimation timer alongside the instructions provided for the order. When comparing possible tank mates, use the tank-mate tool as a starting point and keep a backup plan for territorial or vulnerable fish.
