It's a sealed food box in which I've drilled 2mm air holes around two sides and on the top of one corner (and one larger hole which is usually blocked by cotton so I don't have to disturb them by opening the box every time I need to feed them).
The ants are known to be very dry-loving, so the water tube is going to be placed under the "ceiling vent"). They are still a very small colony of 5 workers and will stay inside the test tube they came with.
Question is, is this enough airholes (and is the arrangement of them okay) to ensure a sufficient airflow in an otherwise well-isolated box or should I drill some more?
