My tank: 55 gallons
3 damels
1 yellow tang
1 percula clown
1 fire shrimp
1 skunk shrimp
1 butterfly henoichu
10 turbo snails
My fish are fine when the lights are on. It's when I have them off for 20 minutes at a time they change color. The butteryfly henochu's stripes turn pale, the tang's fins turn pale, and the clown's mouth turns pale. The color is restored when the lights are on for few minutes (20 minutes). Should I be concerned? I'm afraid to leave my lights off.
