I came home from work tonight to find my betta with a very very odd patch on his head that wasn't there when I left...
I made a recent thread about him being lethargic and put it down to the nitrogen cycle. Ever since I did a 50% water change he has perked up completely and now is (almost to) alert. He is eating as well. I did a 20% water change today. I have noticed over the past day or so that his scales on his head have turned metallic... and now some are falling off
Help, could this be something serious or did he just bump himself? I have has a new ornament in there for the past 2 days (its skull)
