The update is on the colony that's been living in a tub for the past three weeks, waiting for their new formicarium to be built. Well I finally finished it last night for the most part. All I have left to make is the lid. Once that's built, I can remove all the ugly Fluon from the rim.

It's funny what they decided to do with all the Nyjer seeds in their substrate mix. I also noticed they are indeed putting some of these on their fungus.

Since there wasn't room to set their fungus chambers on the ground in the out world, I had to stack them on the tank filler tube. They're all sitting on a lid that's glued to the cap, so they shouldn't fall over. The move process worked well and was pretty easy; now I just have to wait for them to dig their new nest and move in. I really can't wait to see how they dig their nest, and how they grow their fungus in it. I set up a warm light to shine down on them during the day.
For now I have the whole thing sitting in a Fluon-covered tub in case the thing leaks water, or in case the ants escape the Fluon rim. The outside of the tub is coated with Fluon also to keep any Argentine ants from getting to the colony.

I pulled all the plugs out of the containers, to help dry them out a little faster. The last time I let Acromyrmex move out on their own, they continued living in their old containers for months, even without any water source connected to them.

This colony has shrunken a little more, and is quite a bit smaller than my two other large colonies now. Hopefully they'll start doing a little better living in this setup.

I gave them the same little ramp they had while in the tub.

I checked them this morning, and they had already started digging their nest in three different places.
