• Cardinalfish Information
  • Cardinalfish in nice and peaceful fish that can be a great addition to your tank. Cardinals are also one of just a handful of fish that are more active at night time, which could be interesting if you run low powered lights at night.

    Cardinalfish stay rather small and do well in smaller groups. Since Cardinals are so small, it is recommended that they be kept in tanks with lots of hiding places like rock, so if they feel threatened they can hide themselves.

    Cardinals can become aggressive towards similar species, or even their own species in smaller tanks, so please read the detailed information for each Cardinal species before picking Cardinals for your tank.

    Below you can see our full inventory of Cardinalfish that we keep in stock. If you have any questions about any Cardinalfish, please feel free to contact us right away.
