Clownfish question Never seen this

[mojo46825]

Ok MY tank is a 65 gallon. Been setup for about a year. I have had my pair of clowns in there after tank cycle. They host in a BTA. Today I woke up and looked in my tank. The lips on my clowns are white. They will turn to each other and bite there lips. I have seen the quiver shake and do whatever. But not this. The female isnt as bad as the male but not sure what to do. Any help would be great. They are oc clowns.

Try to see if they have been or are biteing at a spot on the rocks near the anemone. They do this to clean a spot to lay eggs and often this can cause their lips to turn white and ragged. Not sure about them biteing each others lips, never seen mine do that.
