Your freshwater aquarium routine

Feed thoughtfully, watch your fish, and keep the water stable.

General care guidance. Needs vary by species, age and health. Your veterinarian can tailor a plan for your pet.

A small daily check

Check fish behavior, equipment and temperature. Keep a record of water tests and changes.

Choose food for the species and life stage. Feed sensible amounts and remove uneaten food so it does not foul the water.

Use an aquarium-specific plan for partial water changes and filter care. Avoid sudden changes to water conditions.

Ask before combining species, adding animals or using treatments. Food and care needs vary between fish.
