Possible to tell the difference between male and female Greissenger Gobies (maybe even breed them?)

So i think the shop has multiple Greissenger Gobies they got in on Wednesday and only cost $27 each. I would consider buying a pair but don't know if they would fight or not...does anyone know? Is there a way to tell the difference between male and female? Furthermore, would it be possible to breed them if the sexes could be distinguished between?

This is the only thing I can find with any info on sexing/breeding them (assuming they wouldn't go for rotifers, they would need Parvocalanus nauplii or similar tiny feed):
So, if you can get a male and female (which it sounds like there may or may not be a reliable way to determine the sex of each, and they might be sequential hermaphrodites), then they can breed, but there will likely be some minor to moderate aggression between them (it sounds like it's involved with the breeding).

Thanks for the link! I was just talking to Matthew Pederson (editor of Coral Magazine and he said at that price if he were trying to breed them he'd grab em all and sort out the pairs later...that would certainly require a bigger tank devoid of predators such as hitchhiking crabs and other hitchhikers though...

Yeah, tiny fish don't mix well with crabs, haha.
