what are all of the difference between male and female Bearded Dragons?
Are males only agressive when another male is around? Which is smaller?

Males tend to be bigger than females but not always the case, it depends on the parents and the bloodline. Males are mainly aggressive when another male is around or when its breeding time.

Males normally have bigger heads,,there are not a whole lot of differences, while the males beard turns very black, the females do also somewhat. Females do more arm waving, where the males do more head bobbing.

Don't forget about the pores...males have more pronounced femoral pores (on the underside of their legs)

Also don't forget that the speed of the head bobbing is different. My Harry(female) bobs her head much slower than Harold(male). Yes I'm back again.
