My tank has been doing fine for 3 months now. Today I for up and went to go watch my clowns. The largest one has a black spot right by his lip. What is this spot. I know it was nto there before... is he sick>>>???? I am real worried about him.
Could you be more specific in describing the black spot.
How big is it? Is it a raised bump or even with skin? How is your fish otherwise...breathing, swimming, eating, behavior?
