Happy Fish Keeper

Happy Fish Keeper helps you keep your fish healthy with a clear and simple care system. Track multiple aquariums, log water parameters, record feedings, and keep notes about your fish in one place.

Create custom tanks with volume, water type, temperature, and equipment details. Explore the included Starter 60L aquarium to learn how care planning works.

Monitor important water values including temperature, pH, ammonia, nitrite, and nitrate. Build a complete history of your aquarium and understand how changes affect fish health.

Each aquarium displays today's tasks, helping you remember feedings, water tests, maintenance, and cleaning routines. Optional reminders keep your schedule organised without becoming overwhelming.

Your aquarium journal connects events, observations, food changes, and new fish additions to overall tank health. Spot trends early and respond before problems become serious.

Whether you are starting your first aquarium or managing several tanks, Happy Fish Keeper makes aquarium care simple, organised, and consistent.
