Blue gouramis, head depression
Recently I have noticed that all my male blue gouramis have developed a strange depression near their head. This has happened to my male blue gouramis, I have other different gouramis in my tank but none of them have developed this depression.
The water quality is good and all of my fish look healthy and are eating.
I have watched closely the tank for any signs of agression but they all seem peaceful.
Can anybody tell me if this is a disease or something else.
