I picked out a male and a female (both 1.5" long) from a large batch at an LFS and put them in a 30g. Is there any real likelihood of them pairing up? They're liplocking like crazy right now - they've been at it for half an hour. They're so tiny, I figured they'd be fine in a 30g. 
Also, they're uber skittish and shy.

So, is there any real likelihood of them bonding and becoming a pair, since they're already fighting so much? BTW, females have a black blotch in the dorsal fin and males don't, right?
