Wierd clown fish behavior

[Squirrelbait]

I have white stripe maroon clowns, and they are acting to me. They claimed the rock tunnel in the tank. And They rub and lay on the bottom, almost like cuddling with each other. I thought they might be sick but not sure. One morning i found one laying on the bottom thought it was dead, so i reached in to get it out and it woke up swam normal. There odd behavior has got me puzzled. Are the mating?

Mine have been doing this too. (Black Australian clowns). I think it is normal, however I have no clue as to what it means or why.
