Pumpkinseeds will compete with YP for some resources but there isn't a large amount of overlap. However, they are fairly prolific, so SMB controlling their reproduction could be a challenge. Unless you really want sunfish in your pond, I'd leave them out.

Stocking fish infested with glochidia could lead to freshwater mussels establishing a population in the pond. Glochidia are generally not harmful to their host fish though. What species are you wanting to stock that are infested with the glochidia?
