We read everything. The most useful messages, in order:

• Corrections: a wrong number with a better source is the best email we can receive — we will verify, fix and update the "Last verified" stamp.
• Calculator requests: tell us the decision you were trying to make; that shapes what we build next.
• Topic requests and sourcing disputes: especially from fishkeepers who think a cited source is out of date.
• Partnerships: aquarium brands and retailers — we disclose every commercial relationship.

Please note: we cannot diagnose sick fish by email. For urgent fish-health questions, a local fish-savvy veterinarian or an experienced aquarium community will always beat an email queue.
