- SEA LIFE Konigswinter, Coral reef
Another big star is the blue tang, also called surgeonfish.
Tangs have a sharp yellow spike in front of their tail root, which they use for both attack and defence. This thorn is also called "scalpel". The so sweet animals are therefore also called surgeonfish.
Surgeonfish are jumpy, so they look for a safe place to sleep at night. This can be for example a nice little hole in the reef into which they squeeze themselves.
Surgeonfish have sharp teeth on the outside of their lips, which they use to scrape algae from corals and rocks for food.
Good defenders, but...
Surgeonfish can defend themselves well, but are very jumpy. So they look for a safe place to sleep at night.
