I think that I would need to add PS first just because I think I could only source them in small numbers. After they spawn, I could add FHM as food. Finally I could add CC at a low density. Adding HSB might be an option for a non-reproducing predator if the PS get out of hand. I like the idea of PS as a novel fish. Of course, I need to actually build this pond, which I can hopefully do during a couple weeks of vacation with the JD550 and some luck on the weather.
