Some what alarmed, yes. It may be nothing more then stress, temp changes, ect or it could be a sign of a respiratory infection. Does he seem active and eating? Eyes opened? Also have you let the seller know there may be a health issue?
Tank is very active, eating a lot and eyes are open and clear. I soaked tank for 20 min this morning plan on again before lights out. We haven't seen any more bubbles. I haven't contacted the breeder but will do that.
