I bought a Betta yesterday, it was a spontaneous thing. I found this gorgeous half moon with a little white patch on his head so I bought him. Welllll..... the white patch seems to have no scales and it looks like an injury. There were no scales in his cup and he doesn’t seem sick or injured. He’s currently in a small critter carrier while his tank clears up and will definitely be able to be moved into his 3.5 by tonight. He is not acting lethargic and is eating well, although he is swimming slowly. His colors are very vibrant too. I’m not sure if I should be concerned, the injury seems quite old.
