I've had a pair of motoros growing up together for the last year, and the male's claspers have developed over the last 2 months or so. They're both about 10", with the female slightly larger (maybe 1" disc) and thicker . Got home yesterday after being gone for a week (parents feeding the rays), and the female's disc is now getting chewed by the male - is this just the beginning of aggression due to the male maturing, or is it possibly the actual start of breeding behaviour?
TIA!
