I just got a stonefish (I belive you guys call them toadfish) today and he has something weird on his head. It looks like someone poured melted wax on his head! I have no idea what this is, and I'm sorry to say I dont have pics. Help!
I know exactly what you are talking about...it is a yellowish/white "thing" that covers the top of the fish..that mass will displace itself to other parts of the top of the fish...mine died after 15 days. Was, still am, clueless.
