I agree with others...what she's doing is creating a smooth surface to lay eggs..the the male will pass over them and fertilize them...then for about 8-11 days, the male will blow them with his mouth and fan them with his fins...while the female "guards" the clutch. After 8-11 days, the fry will hatch at night and swim to the surface...if you were to collect them, you could grow them out...but otherwise, they'll be eaten by mom and dad or other tankmates....consider yourself lucky. Spawning clowns are a great addition to any tank!
