Is there any fish enthusiasts who can help me figure out what's wrong with my betta?
He's losing his colour around his face and at the base of his fin. I've been doing a lot of research and can't figure it out.
He has a 5 gallon tank (recommended size for bettas), he's fed regularly, he has a tank heater to keep it at the recommended temperature (I have a thermometer to make sure), he's the only one in the tank so I know other fish aren't bothering him. He hasn't lost his appetite and he's not lethargic. He's not even an older fish, I've only had him for a few weeks. The only thing I can see that's wrong is he's losing colour.
I cleaned his tank a few days ago, and now I'm worried I might've did something wrong, but I had made sure that I followed every recommendation and direction given to me.
