A lot of the questions and queries that get posted on this forum are to do with Oscar health. In many cases we will be able to help you a lot more if we have something visual to look at. For instance, if you have noticed a strange mark on your Oscars head, please try and provide a photograph on the forum for us to see. It is quite difficult to diagnose the problem just from a description.
Photographs are very easy to post on the forum. Just visit the link below and you will have it up and running in no time at all
