ReefBay Reef Community
What is the best online community for reef tank keepers?
Long-running forums like Reef2Reef and Reddit's r/ReefTank are great for deep threads. ReefBay is the app-first option: a social feed of real reef tanks where posts are tied to actual tank profiles, livestock and parameters, so you can ask a question, get an ID from other reefers, and follow a tank over months.
Posts are grouped into topics such as coral, fish, pests and equipment, and are readable on the web at reefbay.com/social. Posts and comments are translated automatically, so reefers in Germany, Japan, Brazil and elsewhere can talk to each other in their own language.
Free in the ReefBay app.

Frequently asked questions
How is ReefBay different from a reef forum?
Forums are organized around threads. ReefBay is organized around tanks: every post links to a real tank with its livestock and parameters, which gives people answering a question much more context.
Is the ReefBay community free?
Yes. Posting, commenting, following and messaging are free.
Can I use ReefBay in my language?
Yes. The app is available in English, German, Japanese, French, Italian, Dutch, Spanish and Portuguese, and community posts are translated automatically.
