I have four Ranchus that I have only had for two weeks& they are currently bottom sitting or hanging out at the top of the water. Two of them visibly have holes in their head . About a month ago , I lost all five of my fish !! im thinking it was from the same thing.
How do I treat hole in the head?? where and how is that fastest way to get the medicine for it?? I don't want to lose any more fish. Someone please help me!!
