Well, I lost the poor guy today. This morning he was full of energy, and the first to come for food. And the wound was almost completely healed, just a small tiny bit of red that was disappearing, getting smaller and smaller. But when I got home from work, he was floating in the tank. And all his fins were in great shape, and a couple nibbles on his tail. Other than that, no sign of anything, and no open wounds from fish starting to eat off him. And his color was still good, so it must have been just recent that he passed away. He was 2 inches, and looked to be in very good health other than the wound that was almost completely healed. Some things are just impossible to figure out in the fish hobby, lol. All my other barbs are just as happy as can be.....
