Is My Clownfish Acting Okay?

[ThatYellowFJ]

Just recently got my clownfish pair from a fish store last week. Water levels are within the acceptable levels for clownfish, they like to swim up the glass and to the top, or just float in the corner but don’t seem to sleep at night. One of them dart’s pretty fast in random motions from each side of the tank. I can attach a video if need be

Prolly normal. Mine does some pretty random stuff. If i put a new fish in it acts like it. I think it’s because they don't have an anemone but that’s just me guessing.
