As stated in my previous posts, my Molly was spending its time cork screwing and spinning about all over the place. It seams now to have made a complete recovery and is now swimming about happily with the other fish! Was very worried it was bladder infection of something else but the fish seems absolutely fine now. Can it miraculously get better just like that?? I have changed the media and taken out some of the carbonnade changed to ceramic rings as I had too much carbon in it I think.
