I'm going to keep trying with the vegetation. I'm figuring out what I want to try and finding sources for them. With the plants and the crustaceans I'm pretty much in the experimental stage. I may buy another small aquarium or two tomorrow. I have fathead minnows in a 10 gal aquarium now. I'm wondering if they can spawn in it. Scud and Daphnia are supposed to be okay together in the same tank or pond. At worst, it's something to mess with during the winter.
