What Aquarium is

Aquarium Atlas is part encyclopedia, part aquarium planner. Browse 390+ bundled entries spanning freshwater, saltwater, brackish and invertebrate livestock — bettas to tangs, shrimp to clownfish. A matcher quiz finds fish that fit your tank size, experience and water; a compatibility checker flags bad tankmate combinations before you buy; and planning tools estimate stocking levels and setup costs. Once running, track water parameters and maintenance so the tank stays as healthy as the plan.

What it does

  • 390+ bundled species entries across fresh, salt and brackish water
  • Fish matcher tuned to tank size, water and experience
  • Tankmate compatibility checking
  • Stocking and setup cost planning
  • Water-parameter and maintenance tracking
  • Offline-first bundled catalogue

Compatibility is the whole hobby

Most aquarium heartbreak is a purchase that should never have shared a tank. Aquarium Atlas checks the combination before the shop does — against temperament, water chemistry, size at adulthood and territorial habits.
