sera guide - Healthy aquarium fish

The contents of this guide were compiled by an expert team with all required care and ac- cording to newest scientific findings. Never- theless, this short brochure can only give an overview about the most common fish dis- eases and their causes. Rarely occurring dis- eases or those that cannot be treated at all or only with support from a veterinarian (e.g. ul- cers caused by cancer, nerve damages and genetic deformations) are not included here. In such cases, we wish to refer you to further specific literature, e.g. to the easily under- standable and abundantly illustrated book, “Krankheiten der Aquarienfische” by the sera specialist Dieter Untergasser, issued by the Kosmos Verlag (available only in German lan- guage). 2 Recognizing fish diseases Please note that the chemical and biological conditions in different aquariums may differ very strongly. It is therefore not possible to precisely predict the exact reaction for each single aquarium and for each animal species. This in particular applies if chemical sub- stances have entered the aquarium with water, organic pollution or previous treatments and might cause unpredictable cross reactions with the treatments. A general warranty and li- ability for personal injuries, property damage or financial loss due to the treatment sugges- tions in this guide is therefore excluded by the editor. You will find extensive advice about setting up and maintaining your aquarium on our Internet site www.sera.de or in our numerous guide booklets. 6
