There's a diamond in the rough here. If you decide to rework it, I would suggest a few things:
1. As mentioned in other posts, vivisection is unneccessary when dissection of deceased specimens is much more humane and provides similar if not identical information.
2. You mentioned sapience and a language, which is cool. Make use of it! This is a significant part of what makes the anomaly interesting. Put in some interview logs, maybe show the doctor interacting with them and use it to introduce the exposition about his daughter more naturally.
3. I seriously doubt the Foundation of all things would just accept sapient aquatic bugs and append an -ex to them. Probably not keter, but definitely at least a euclid level thing.
4. Add some details about their society, if they have one. They're bugs with human level intelligence and a demonstrated language, so their social lives would absolutely be of interest here.
Don't shelve it yet, this one has a lot of promise. No vote for now
