I have just converted my 55 gallon south american tank to an African tank. I had a zebra and an auratus in seperate 20 gallon tanks upstairs. I went and got a couple of small assorted africans and added my 3-4 inch zebra to the tank as well. Over the last couple of days I have noticed that there is this white almost fungus like stuff growing only around his eye and in between them. Now he is just hiding on one side of the tank behind some big rocks and is not eating anymore. I have never had anything like this in my tank and have no idea what I need to do. Has anybody else had something like this happen? Could it be just from stress and moving him into a new tank? Any ideas would be greatly appreciated. Thanks in advance.
