Tips for choosing fish
When selecting fish for your aquarium, consider the following:
- Tank size: Ensure your tank meets the minimum requirement for each species, accounting for adult size and swimming space.
- Water parameters: Temperature, pH, and hardness must overlap for all species in your tank. Use our compatibility checker to verify.
- Temperament: Peaceful fish do best with other peaceful species. Semi-aggressive fish need space and proper group sizes.
- Social needs: Schooling fish need groups of 6+. Some species are best kept singly or in pairs.
- Experience level: Beginners should start with hardy, easy-care species. Advanced keepers can tackle more sensitive fish.
