TL;DR
Would there be an interest in the community to begin setting up these experiments and studies as a group activity. There's many aspects and topics within this thread. Perhaps if it was broken down, each set up as a thread, and members sort of "signed up" for each study. We'd need a set standard and have impeccable record keeping for each study from each keeper. It would be a huge endeavor, but could lead to a world-wide multi-species studies conducted that would give a range of results to help better understand the hobby. This is something that I've seen happen in the aquatics community that can potentially provide newfound and incredibly useful information.
I think the hardest part of organizing this is the fact that ant colonies have a very long life cycle. Multiple generations of fish can be reared in a year, whereas ant colonies take time to grow. It would be a years-long project.
