I've had success with these little acrylic/gypsum founding formicaria, they have water towers. https://www.aliexpre....27424c4dvKjqfK I give them a good rinse before use. Cut a piece of the supplied tube to put between the nest and outworld, there can be a gap without it. They've worked great for me for multiple species of Camponotus and Pogonomyrmex. I love the THA stuff for display and larger colonies, but these cost less less than 20 bucks apiece. I've been attaching a test tube cotton/water setup to the outworld port for hydration, and dropping a liquid feeder for sugar into the little outworld. Be aware the lid can't move side to side, but is only held downward by gravity.
I also like these little outworlds, nice clear acrylic and a built in lip around the top that with the help of some fluon is great for preventing escapes at feeding. Acrylic with lid feeding box Feeding box Spider box Kun reptile box Ant nest Ant 12*6*9 cm|Insect Supplies| - AliExpress I've started attaching these to my bigger THA nests for feeding rather than opening the main outworld every time. The seller has them in 3 sizes, the tall one is a bit too tall to reach down into comfortably. Looks like they have an even larger one now, I haven't tried that one yet. I put a little grout and a nice rock in the bottom of them.
Aliexpress has been pretty hit or miss for me. Sellers that have no or bad reviews should be avoided. Stick with sellers you know others have used with success or that have a good long track record. Sometimes what arrives is very different than the picture. Know that if something arrives broken or never arrives at all you'll get a partial refund at best. I've ordered four of the formicariums I linked without issue, and two of the acrylic boxes.
