Sexy time or eating each other... Hermits

[Rick's Reviews]

my wife sent this video this morning so i apologies as for some reason I can not share unless via other platforms..

Are these guys just looking to mate? I introduced 5 of over a month ago and only had 1 loss, just recently they have been acting differently, I understand these hermits grow shells like snails,
My aquarium has 2 clowns, high fin goby, pistol shrimp (paired) cleaner shrimp, strawberry nosed conch. Big haiwian legged crab that's moved shell again but happy grazing so far, snails and various hermits.

Just these guys seem to be chasing each other down, they skip over smaller of same species to wrestle? Sexy time or hungry,
Thanks

Not positive but in my experience when I saw that happening with mine 2 ended up dead the next day. And one (who im assuming to be the killer) had a new shell that was from one of the ones that was killed
