Before I got into shrimp I was breeding Darts. The tads are pretty easy to raise. Probably the only issue I had was making sure I had food on hand at all times. At one point I was raising two different types of fruit flies, Wax worms, some kind of beetles, and getting crickets for them. I even went as far as getting termites for them when I could find them. All in all I had 8 different species in a 6 year time frame. Got all but one to species to breed.
