Courtney Morgans (Ord Lab, UNSW) stated: "The two males were displaying at the same time, I didn't see either of them act in a physically aggressive way to the other, they were just trying to out-compete each other for the attention of females. I'm not sure how long it takes for a male to achieve colour change from cryptic to conspicuous as they tended to be quite shy. If however, I disturbed a conspicuous male it would take about 15 seconds for his colouration to change back to the cryptic form."
