Reeflex

Dear visitor,

Welcome to reeflex.net, the interactive online encyclopedia for marine life worldwide, founded in the year 2000 by a group of enthusiastic reef keepers.
Over the years and due to the brilliant underwater photographers and marine experts it has developed into a comprehensive database for the identification of marine animals and plants for all interested people.
As an interactive online encyclopedia reeflex.net lives on the shared experience of its users, whether they are divers, saltwater aquarists or other people interested in marine biology. We welcome you to attribute your images and comments.

The intention of reeflex.net, however, is to provide a serious and reliable source of reference for all its users. Please note that we only accept useful contributions with a well-sounded basis in knowledge or experience as well as high-quality images. Any comments not matching these criteria, containing obviously wrong information, etc. may be deleted by our administrators without notice.
Once again thank you very much for your interest. We hope that you do enjoy your visit to reeflex.net

The encyclopedia is visited by up to 11,000 visitors daily; last year, the Marine Encyclopedia recorded 4 million visitors with 81.9 million page views.
As of 2026, there are over 17,000 entries on marine life in the Marine Encyclopedia.

An important note regarding the number of litres in the lexicon: It is difficult to specify the optimum number of litres for each animal. It can only be understood as a rough starting point. The various individual factors, such as the pool structure (decoration), the entire stocking and the available swimming space, which play an important role, must be taken into account. It is therefore in the interest and responsibility of every caregiver to determine this in detail beforehand!

Your reeflex team
