I noticed that his chest is rising and falling very fast. Is this anything to be concerned about?
As noted by others respiration of 120 per minute requires an immediate visit to the Vet. Normal Respiratory rate for rabbits is 30 - 60 breaths per minute.

Observation I am sitting in my home office with my rabbit & my laptop on my lap. The Temperature in the room is 77, my feet are up on the desk and I am reaching over the rabbit to type. I looked down and notice she is breathing more than twice per second (i.e. 120+ per minute). I took her back to her room where it is cooler. A few minutes later she is resting on the floor and has a normal respiration rate. It would seem that like many other furry animals rabbits breath faster when they are warm. If your rabbit may be overly warm take a look at How can I keep a rabbit cool?
