he is excited when he sees you and is eager for food .perhaps feed him her more .i have had mangrove jacks that have white noses after a while ..how mutch and wot are you feeding it? i dont think its sick . if you poke your head around the corner and look at it while it doesnt see you it wont be doing it ...let me know : oh and if you can just check to see if it isnt looking at its own reflection. just change the angle of your light and see if it stops it .
interested in your reply
