So I have a Greater Siren as a temporary house guest (he better be temporary... If I fall in love I'm screwed), and I have seen him every few months for years. He's had this unusual grey matter on his head forever, it gets slightly bigger over the years and the unusual orange cyst-looking things are kinda new to me but likely have been there, slowly appearing.
Does anyone have any idea what these could be? If they are tumors, then, well there's not much I can do about that. But if this is a parasite or a fungus I need to know, because I have another siren in another tank and I need to know how paranoid I should be.
Any info would be helpful! Ready to answer questions as detailed as I can.
