Dear visitor,

Welcome to reeflex.net, the interactive online encyclopedia for marine life worldwide. It is currently available in ten languages. Founded in the year 2000 by a group of enthusiastic reef keepers the reeflex community’s aim originally has been to collect and to share information on the husbandry and behaviour of marine fish, invertebrates and corals kept in captivity.

Over the years and due to the brilliant images well-known underwater photographers have contributed, it has also attracted more and more recreational divers who, in turn, attribute their photos and comments on their sightings to reeflex.
And so reeflex has developed into a comprehensive database for the identification of marine species.

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, and we welcome you to attribute your images, videos and comments. The intention of reeflex.net, however, is to provide a serious and reliable source of reference for all its users, so please note that we only accept useful contributions with a well-sounded basis in knowledge or experience as well as high-quality images or videos. Any comments not matching these criteria, containing obviously wrong information, etc. may be deleted by an administrator without notice.

reeflex.net is not a platform for discussions. If you have any questions about care requirements of an individual marine species or the setup of your tank, you may use the shout box in the column on the right-hand side. Alternatively you can post your question in one of the numerous reef keeping forums.

As you will see the general information for every listed marine species which may be kept in captivity contains recommendations on the size of the tank. These are meant to serve as a guideline for you. Although these recommendations are based on the long-term observances of experienced reef keepers, it is rather difficult to determine the correct tank size, since the well-being of marine fish, invertebrates or corals in captivity is not only dependent on the mere size of the tank, but also closely associated with how the tank is structured, how much swimming space will be available as well as what kind of other marine animals are already living in the tank etc. It is in the interest of each responsible reef keeper to thoroughly inform himself and to check whether he will be able to fulfill its needs before he introduces a new animal into his tank.

Once again thank you very much for your interest and we hope that you do enjoy your visit to reeflex.net

Your reeflex team

Hallo Corinna!
Ja - es ist der einzige der diese symptome zeigt 



From: CoralReefNow
Topic: Stylophora pistillata
Die Koralle sollte hell stehen, man sollte trotzdem aber darauf achten, dass man es mit dem Licht nicht übertreibt, da sie sonst schnell Verbrennungen zeigt.
Das Wasser sollte immer Klar sein sonst öffnet sie sich nur selten.
Habe die Erfahrungen gemacht, dass die Strömung keine große Rolle spielt.

Hallo Panda,

sieht nach Einblutungen unter der Haut aus, dies könnte auf eine bakterielle Infektion hindeuten.
Ist er der einzige Fisch in Deinem Becken, der diese Symptome zeigt?

Viele Grüße

Hi aw.Uschi,
vielen Dank für Deine Bestimmung, es geht hier bei der Frage jedoch nicht um die Koralle, sondern um eine unbekannte Krabbe.

Hallo Hille,
dass Foto ist für eine Bestimmung leider nicht deutlich genug.Zumindest kann ich nicht wirklich was erkennen, außer es meldet sich noch jemand, der damit was anfangen kann.
