AquaNexus: Aquarium Manager

ONE APP. EVERY AQUARIUM.

From your first tank to a full fish room.

AquaNexus brings your tanks, livestock, water, breeding, treatments, equipment, maintenance and aquarium history together in one organised app.

No account required • Works offline • Built to grow with you

Whether you're setting up your first aquarium, keeping several tanks, breeding fish or shrimp, managing ponds, or running a larger fish room, AquaNexus gives you one place to keep track of what matters.

MORE THAN A WATER-TEST LOG

• Manage aquariums and ponds with dimensions, calculated volumes, environments and locations
• Keep livestock records including quantities, life stages, movements and history
• Record water tests with warnings, trends and practical guidance
• Track water changes and build a complete maintenance history
• Manage medications, treatments and dosing records
• Track feeding, breeding and routine maintenance
• Manage plants, lighting and CO₂ records
• Keep equipment, supplies, servicing and warranty records
• Track aquarium photos, reminders and timelines
• Create source-water profiles for the water you use
• Keep sales and historical aquarium records together

BUILT FOR THE AQUARIUMS YOU KEEP

AquaNexus supports freshwater, planted, shrimp, coldwater, pond, brackish and marine systems.

Start with one aquarium and keep using the same app as your setup grows into multiple tanks, breeding systems or a full fish room.

Your Home screen adapts to your setup and experience, keeping relevant tools easy to reach.

BUILT FOR BREEDERS TOO

Keep breeding activity connected to the tanks and livestock it belongs to instead of spreading records across separate apps and notes.

Track breeding, livestock history, fry, maintenance, water, feeding and sales as part of the same aquarium workspace.

YOUR DATA, YOUR DEVICES

AquaNexus does not require an AquaNexus account or login for normal use.

Your aquarium records are designed to remain on your device, and most record-keeping features work offline.

Create local backups, restore your data and securely connect approved AquaNexus devices over your local Wi-Fi network.

Master Transfer can move a complete AquaNexus workspace between approved devices.
