All fish have pros and cons in the pond ecosystem. There are numerous fish species that have not been intently studied as much as LMbass and BG for how these less common fish species will perform in the pond niche with other species. A lot about various fish combinations is still to be learned. As Shorty suggests stock the OSS, watch the results and be welcome to return and report your observations with the OSS in your pond. That practical research is one good way how we learn more about fish pond management.
