Yes they will tussle. As said in another post I have 3 males that are aggresive breeders and when places with certain females (not all) they do seem to try and "beat" the girl into submitting to him and letting him breed her. When I first seen and heard this going on I was scared and was unsure of what was going on cause I knew the sex's where right and they only seem to do it to certain females. (And yes these females heve bred with other males before so I know they are females) I guess they just like it rough! LOL
