I guess within the next month I'll start to see some aggression.. but I've never had a spawn before so I'm not too sure.

As far as I know, boys will eventually act like all males do regardless of whether it's related to the other male or not. A friend of mine put two of her juvies together to try to figure out if she had a male or not (couldn't tell by the oviposter or fins). Both were flaring like crazy and trying to attack (would have if she hadn't removed them) even though they were related.

Females though, I've heard generally get along with their siblings if raised and kept together. Of all my females I've ever had, 3 refused to accept other girls.. so it'd be nice if female siblings really do get along.. cause that'll mean less cleaning for me.
