Fish Explain exists to give people clear, accurate and useful information about fish. This page explains how we research, write, check and update everything we publish.

How we research

Every article starts with trusted primary sources. For species facts such as size, lifespan, depth range, diet and conservation status we rely on scientific databases and organizations, including:

• FishBase, the global database of fish species
• The IUCN Red List for conservation status
• Peer reviewed research, university extension services and government agencies such as NOAA and the FDA
• Established aquarium and veterinary references for fishkeeping advice

When sources disagree, we say so and explain the range instead of picking the most dramatic number.

How we write

We write in plain English for curious readers, beginners and experienced fishkeepers alike. We answer the question first, then explain the details. We avoid hype, and we never present a guess as a fact.

Fact checking and review

Before an article is published, its key facts are checked against the sources listed at the end of the article. Health, nutrition and food safety topics get extra care, and we point readers to a qualified professional where that is the right answer.

Corrections and updates

Science changes and mistakes happen. If you spot an error, please tell us through our contact page. We review every report, correct confirmed errors promptly and update the date shown on the article.

Independence

Our recommendations are based on research, not on payment. If we ever earn a commission from a link or accept a sponsorship, we will label it clearly on the page where it appears.
