Eggs, eggs, eggs... oh, N' some diggin

They little buggers have eggs, Ive seen at least 5 eggs.

All the ants (that I've seen) are the same size, so im 99.9% sure there isnt a queen. Still, they have started digging now tht ive covered both sides over with card.

Ive just noticed that there is a gap at the bottom of the card and I can see ants scurrying about at the bottom of the tank. cool :D

I havent got a pic of the eggs yet, but there is a bigger version of the pic to the left here.
