It is relatively easy to have fish survive on there own in a pond. It all depends on what you want. We pretty much leave our BG, RES, LMB pond alone and it provides a lot of BG for the neighbor, and a lot of fun for kids that want to catch fish. We have a "natural edge" on the pond that was started with planting the emergent plants that we wanted, and removing willows and cattails. We also have domestic water lilies. One can manage a pond for a desired outcome, or one can go with the flow. It is important to add fish of particular species in a particular order if you want compatible species. Otherwise, one species may result in another going extinct in your pond. I will leave it to Texans and other experts to give local advice. The most important thing is to enjoy your pond.
