alWelcome to R2R, there is not an easy way to say this but clownfish are weird!
I have a pair that are hosted by the back top left corner of my tank and another the front bottom right hosted by a frag rack!
They look fine and good to see them together.
Alright thank you very muchWelcome to R2R!
This is quite typical behavior for clownfish. Give them time and they will start to roam some. But they are quite territorial and tend to protect a small area.
