My Wolf fish has been acting lethargic and it's fins have been kind of clamped. Also, the black dots on its fins and stomach have been a lot darker than usual (it changes color all the time but I've never seen the dots like that before). It has been eating well, so I'm not sure what's wrong. I could just be paranoid but it's my favorite fish so I wanted a second opinion. I'll post a picture as soon as I can but for some reason it won't upload.
