I have 2 gsp & for the last couple days one of them has turned a blackish color & not looking to good. He pretty much stays this color except he'll change back to normal when I feed them, but then goes right back to blackish again. Today he hasn't wanted to eat. I'm wondering if maybe his teeth are too big or something, I really don't know, I've read so many different articles from their teeth, if it's IP, stress, etc... If anyone can help, I & I'm sure he would greatly appreciate it.[/img]

What are your water parameters, tank size, tankmates, how long has the tank been set up, how long have you had them, how did you cycle the tank? Need more info to be able to help.
