one of my baby indo Datnoid have this swollen bump around the eyes and mouth. I think its fungus but not too sure if I am right so can you please tell me what is it? and what kinds of treament should i use for the poor little guy? the fish is eating just fine and still chase other datnoid no signs of him being stressed or hard breathing anything but I really want to make that bump on its mouth to go away. Here are some pics I apologize for the bad quality pics I took with my phone.
