They live almost all over the US, but the trick is to find waters where the
fish don't eat all of them. In Calif. our regular spring rains fill ponds that
dry out in fall, and the daphnia outproduce the fish fry for the first few
months. By summer they are gone. Try Lake Lagunita on the Stanford campus, in
May, for example. Ponds without fish are very rare -- someone will introduce an
entirely unsuitable "mosquitofish" for sure!
IDK when or where you can find such waters in a place like Texas. Look for
temporary, recently-filled ponds for the most likely places for them. In the
southern part of the state, it may actually be too tropical (and too flat) for
them, and they may be more rare.
For purchase, most of us rely on the local aquarium societies or specialized
local fish clubs for live-food starters. Carolina Biological supplies
researchers with many live cultures, and the American Killifish Association has
them in their Business Newsletter, from time to time.
Good luck,
