Saltwater Fish Compatibility Checker - Reeforia
Reeforia is a free saltwater aquarium compatibility tool that helps reef hobbyists check if their fish, corals, anemones, and invertebrates will get along before adding them to their tank. Build your virtual reef tank and instantly see compatibility scores for every species combination.
How It Works
Simply add livestock to your virtual tank and Reeforia will analyze compatibility against every other species. Each pairing is rated from "Great Match" to "Not Compatible" with detailed notes explaining why, such as territorial aggression, chemical warfare between corals, or predator-prey relationships.
