I don't think they're a true M-F pair due to the white line, but I've seen a youtube video of Cr. sp. Venezuela working together in a group to fight a buttikoferi so that might explain why they seem like a pair. Nice fish though, but make sure you get the HITH under control...

HITH is Hole In the Head....Treatment involvese frequent water changes, and try to get them on pellets or something with a good nutrient base.
And no you wont vent them. The white line down the dorsal is the way to sex this type of pike.
