I see some mucus plugs - lower right and upper left. See how they come to a smooth point? If that's what they are, these are a result of some stressor. Sometimes, these are from a parasite, but when I see them on the face of a clownfish, I always wonder if they are a result of "biting" with another clown. I see the much smaller male, but he must be really tough to take on that big momma! Still, clowns do have weird dynamics when it comes to living together and maroons are the worst for that. You may well never see any biting actually happen, since clowns are so alert that they stop fighting to watch you when you are in the room.
Do the two fish still seem to have a good pair bond? Do they sidle up next to each other most of the time?
