Choose fish for your aquarium

Check the particular species' adult size, group requirements, water conditions and compatibility with your existing fish before choosing. Tank space, swimming activity and fin-nipping behaviour vary between species, so a shared tetra name does not mean identical care or suitability for every community aquarium. Ask our team to help compare options for your setup.

This collection also includes Spotted Rasbora, a separate freshwater fish rather than a tetra. Refer to its individual listing when comparing care requirements.
