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 |
Browse by fish family
Use the catalogue routes to compare fish with a similar role or body plan:
- Tetras, rasboras and danios for active mid-water groups.
- 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.
Frequently asked questions
The fish-only grid includes tropical tetras, rasboras, danios, barbs, livebearers, corydoras, plecos, loaches, gouramis, angelfish, cichlids, rainbowfish, killifish and other aquarium fish. Shrimp, snails, crabs and amphibians use separate collections.
