In ponds spotfins are much more prolific than spotails. Some work needs to be done with spottails to determine how well they spawn in pond habitats. Pond spawning characteristics of spottails in the literature is almost non-existent. Emerald shiners will not spawn in normal non-flowing water ponds. Numerous Lake Erie minnow sellers have experimented with emerald shiners with no success.
I think the other spotfin related shiner called the steelcolor shiner would be a good pond spawning species; max size 6.3".
Snipe since you are west of the MIssissippi Rv I would seriously consider the more western area red shiner Cyprinella lutrensis max size 3", spawns in reservoirs, tolerant of harsh conditions like turbidity, wide temperature and DO range.

Spawning season of C. lutrensis is from spring to fall and the peak is during the mid-summer months. Crevice spawner similar to the other Cyprinella species. Females may release up to 16 batches of eggs per day, with up to 71 eggs per batch. An average clutch size may equal around 585 eggs and males and females may spawn 5-19 clutches over the reproductive season (Gale, 1986). Laser and Carlander (1971) reported that 485-684 eggs were laid per gravid female.
Red shiner is a faster swimmer than the FHM and might not tolerate bass predation very well. But probably a very good forage species for YP and WE.
