I'll add native crawdads once I get my plants established in the new pond, but they will probably get there on their own in some numbers before I do this. I'd like to add shrimp, but am not sure how source them locally. I'll need to do some netting of plants and see what I find. I will also be catching small fish in our creek when it warms up and will post pictures before releasing them in the new pond. I appreciate you volunteering to ID them!
