Ok so time for an update. The sore on his head was starting to look infected again, so I ended up taking some advice from a local breeder friend. I treated the spot with betadine. He was calm when I pulled him out of the water, calm when I treated the spot, but when I tried to release him from the net he freaked. Anything whithin about 10’ of my tank got soaked, including our router and knocked out our internet for a time. It took a few treatments so it was pretty stressful for both of us. I was really questioning if I did the right thing or not, heart racing and just sick to my stomach. He was sulking in the corner after each treatment but I tried to cheer him up with different treats. The past few nights he seems to go hide in his little corner and not move, as if he figures he doesn’t move I don’t see him. I think he feels like I am going to keep treating this wound. He is usually active and swims around playfully during the day.
