I noticed today that my bi-color pseudochromis doesn't look the way he usually does and it has me concerned about the other fish in my tank. He typically has a very vibrant pink/yellow color to him, however today he is looking a bit pale and blotchy. His entire lower jaw is white and the rest of him is pale. His personality is the same. He is very active, ate food and does all the things he typically does. Any ideas what could be up? The last new fish I introduced to the tank was a Coral Hawkfish about 2-3 months ago. In the year and a half I have had this tank I have never had a sick fish or any other sorts of illnesses. Water change was done last night. Did not get a chance to do chemical tests yet today. Thanks everyone!
