Stop guessing. Start thriving.

Mahiyar is the aquarium management app built by fishkeepers, for fishkeepers. Whether you are setting up your first freshwater tank, managing a saltwater reef, or juggling multiple aquariums—Mahiyar gives you the tools to keep every tank healthy.

Key Features
Stocking Calculator: Our advanced bioload engine goes beyond the outdated "inch per gallon" rule. Get accurate stocking recommendations based on your tank size, filtration, and the actual needs of your fish. Works for freshwater community tanks, cichlid setups, reef aquariums, and planted tanks alike.

Water Parameter Tracking: Log pH, ammonia, nitrite, nitrate, temperature, salinity, and specific gravity. View trends over time so you can spot a water quality problem before it becomes an emergency. Built for freshwater and saltwater parameters.

Proactive Alerts: Mahiyar monitors your water logs for dangerous trends—ammonia spikes, nitrite climbs, pH swings—and gives you instant, step-by-step action plans to protect your livestock before it's too late.

Cycling Assistant: New to fishkeeping? Mahiyar walks you through the nitrogen cycle step-by-step, tracking ammonia, nitrite, and nitrate so your aquarium is fully cycled and safe before your first fish goes in.

Drip Acclimation Timer: Introduce new fish safely with the built-in drip acclimation timer. Smart notifications guide you through each step, even for multiple fish at once.

Fish Species Database: Browse 1,000+ freshwater and saltwater species with detailed care guides, water parameter requirements, and compatibility alerts. Prevent aggression and stocking mistakes before they happen.

Maintenance Reminders: Set recurring reminders for water changes, filter cleanings, and dosing schedules. Never let a maintenance task slip.

Multi-Tank Dashboard: Manage every aquarium from one clean dashboard. Each tank gets its own water log, fish list, maintenance schedule, and health history.

Dosing Calculator: Calculate precise doses for fertilizers, medications, and water treatments based on your tank's exact volume.

Activity Logbook: Track water changes, feedings, new fish additions, and more in a searchable timeline. Build a complete health record for every tank.
