I got my betta maybe a little over a week ago. I did get him at walmart so there is no telling how he was before.
Ever since I've had him he hasen't been eating. He'd just spit out food. Now he won't even put it in his mouth.
People have told me it sometimes takes 1-3 weeks at most for them to adjust to a new tank.
I just did 50% water change for the first time today.
I've noticed him also just acting lethargic. He also won't flare up at his reflection in the mirror anymore. I checked the temperature and it's fine. I also did a test on my water and everything is normal.
I looked up symptoms of sickness and I'm so inexperienced I think he has everything, out of pure panic.
I think he's either been biting his fins or he's got ick or velvet. I really don't know. Here is a picture, can someone help me?
I'm shining a flashlight on him to check for Velvet and I'm not sure if he has it because it's a gold color.
