Have noticed a few white furry like spots on my large convict. He is approx 1 year old and I am really new to this fish malarky so I was wondering if anyone could shine some light? I tried taking some pics but can't seem to get any decent ones. The spots on located on his front fins around his gills and possibly on his tail. None of the other fish in the tank seem to have this, including another convict. Any ideas? Cheers.
