They are both about 5mm long.
Sorry if the photos aren't the best. I don't have a camera with good macro lens.
I primarily want to know if they are claustral or semi-claustral. I'm assuming claustral due to how small the head and mandibles are, but would like someone more knowledgeable to give me some feedback.
These are some of the smallest ants I have seen in my area and really want to take good care of them. This is my first attempt at starting a colony. They are both in test tube setups and seem to be doing OK at the moment.
