What you will find here
Our blog sits next to the main guides. The guides are reference pages: a full species profile, a step-by-step care routine or a complete troubleshooting page. Blog articles are shorter and start from one question, the kind you type into a search bar late in the evening while watching your tank.
Every article follows the same editorial rules as the rest of the site: widely accepted ranges rather than false precision, no invented tests or statistics, and a clear line between normal behavior and a problem that needs action.

Where to start
If you are new to the hobby, read our beginner aquarium guide before the articles: most questions about lifespan, behavior or breeding come back to the same basics of a cycled tank, a stable temperature and regular water changes. Betta owners can then go straight to the article on how long betta fish live, and anyone curious about night-time behavior to do fish sleep.
