Hello! I have around 15 powder blue dwarf gouramis and three three-spot gouramis. Surprisingly, I lost two powder blues this month. The first one developed what looked like a broken/bent back but continued to live for about a month. I thought it was genetics but within a week it quickly declined and passed away. I had a second gourami that began to look extremely skinny with uneven bumps (almost like protruding ribs). I did a full General Cure treatment but wasn't able to save him. I looked at different diseases and came across Dwarf Gourami Disease. Recently I have begun to notice other signs on a few of my other gouramis that match the description of this virus. I have also noticed small holes near their head and some (one in particular) have started developing red patches. I was wondering if someone could confirm this as Dwarf Gourami Disease or something else. If it is DGD, I've heard that there is no cure/treatment. Is this something that is going to run its course and I'll have to start over? If so, how could I best prevent this from being transmitted to my next fish, even if they're not gouramis? Thanks in advance!
