Great stuff mate.... Looking good..
Thanks, i got my ants coming tomorrow so hopefully they will move in to the block after a while as i have heard myrmica rubra sometimes don't like ytong.
Thats balls matey.. i've always kept mine in ytong and they grow fine in it.. in fact i had to make a second ytong for mine as they outgrew the first!
