Hello, an outworld for my Myrmica sp. finally arrived, however, its port is 10 mm ( and there wasn't a bigger option ), same as my tubing, while my test tubes have an opening of 15 mm, so, obviously, what I need to do is to insert PCW tube into my tube with some cotton blocking the openings, however, while attempting that with an empty tube, it was very, very hard to do, how do you guys do it? Especially without stressing the ant too much.
