Tumor? Growth? *pics*

[krzr3000]

This mbuna has had this growth for about a month, progressively getting larger. Any ideas as to what it is or treatment if possible? The fish is still eating normally, and tends to hide out in the same area of the tank. But that could be normal mbuna behavior anyways. Sorry about picture quality.

Thanks
