Green bubble annenome

[Richards Aquarium]

I have 2 of these the one is the dark green as the day I got him and the other is Turing a really light pale green when opened and when he closes up he is darker. The one who's is dark goes behind center rock and the light one stays out in the front. Any ideas ????

Gene expression. I wouldn't worry about it. My anemone gets bigger and darker at night, but he's also just fine during the day.
