My powder blue which is doing fine and eating well all of a sudden has this black dot (it doesnt look like black ich). Its only one black dot here are some pics.

Your PBT looks beautiful. I would leave him alone until he seems weird or the spot becomes larger.

Thank you so much. I looked at him this morning and that spot has turned white. Its really weird. Its Asymmetrical (on both sides) but it might be going away. Other then that he looks good, so I guess your right lets see what happens!
