Is this normal behavior?

My clowns have been swimming on the top right corner for the tank for atleast a day maybe 2 days. Usually swim around the tank. Is this normal?

Are they eating normally?

My clownfish unfortunately do something similar: are in one corner 90%+ of the day and night

clowns generally pick a spot and claim it as their own. This could be an anemone, a powerhead, or just a corner they like for whatever arcane reason. This is normal and not concerning on its own. However, the clown on the right looks to be gaping its mouth, which can be a concern. Is that something you've observed often or just a one off during the photo?

Clowns just being clowns. Yeah, they do stuff like that.

I can’t say yours are OK, but sounds like typical clowning around by your clownfish.
My clownfish hang out wherever I park the magnetic glass cleaner.
