Freshwater Aquarium Master Keeper — Interactive Digital Tracker
Manage your freshwater aquariums in one place with the Freshwater Aquarium Master Keeper — a downloadable interactive tracking system built for everyone from single-tank keepers to multi-tank hobbyists, breeders, and fish rooms.
Unlike a traditional printable planner, the Master Keeper runs locally in your web browser and lets you add, edit, organize, and maintain your aquarium records over time.

Built to Grow With Your Hobby
Start with one aquarium and use only the basic tools you need. If your collection grows, the same system can expand with you — whether you're adding more tanks, keeping larger livestock collections, breeding fish, raising fry, managing shrimp colonies, or operating a dedicated fish room.
Your Records Stay With You
The Master Keeper is local-first. Your aquarium records are stored on your device through your browser rather than in a HabitatCraft account or online database. Built-in backup, restore, and export tools make it easy to keep copies of your records and move your data when needed.
