I think whatever you end up picking as your design topic, focusing on tropical hosting anemones could have an added impication to assist with keeping the hobby viable. As I'm sure you know, each year there are more laws proposed here int he US to try to limit the importation of many coral species. It is only a matter of time before this happens for anemones as well.
One of the biggest problems these laws have is that they are not based on much more than opinions. Unfortunately, standing up against public opinion is difficult, and requires irrefutable evidence. Certaintly pushlished data greatly assists in this defence of our hobby.
I'll reiterate what I and OrionN said earlier - please keep up updated. There are several extremely knowledgeable individuals on here that could really help you steer your research and provide useful insight. I think the interesting thing with your topic, is that much of the current data on said species may not be in standard published literature, but rather scattered throughout the internet. This makes searching and finding the truth quite difficult, and citing even worse.
However, I found in my dissertation work that having those discussions with the experts can help steer you to find a citable source, that you can then corroborate with interview citations. It gives two sources that are otherwise individually a little weak a bit more strength - sometimes the data you need to cite and discuss just flat out is not published.
Good luck!
