Thanks, guys!
Jess was spot-on with sexing them too...she PM'd me some pics before sending them, and sure enough, they are just as she told me they would be.
I put the 'third wheel' (non-paired female) into my 38 gal.---now planted---a couple days ago. I'll keep you updated on how the plants do (mostly green hygro and wisteria, along with some wendtii and petite nana).
On another note...the parents moved the eggs, which are now wigglers!
