About AquaMateCheck

AquaMateCheck is a free fish compatibility checker designed to help aquarium hobbyists avoid costly mistakes. Our tool analyzes water parameter overlap, temperament match, and size predation risk to give you a clear verdict: GOOD, CAUTION, or RISKY.

Our Data Sources

• FishBase.org — Global fish database with scientific data on temperature, pH, size, and distribution.
• SeriouslyFish — Expert forum data on known compatibility conflicts.
• AquariumStocking — Bioload calculation methodology.
• IUCN Red List — Conservation status for endangered species.

Accuracy Disclaimer

Individual fish behavior varies. Our tool uses expert rules and scientific databases, but no algorithm can predict every situation. Always quarantine new fish for 2-4 weeks, observe behavior, and avoid overcrowding.

Why We Built This

We noticed that all existing fish compatibility sites had low authority (DA < 30) and used outdated forum posts from 2014. AquaMateCheck uses structured scientific data and real-time calculations to give accurate, instant results.
