It will be interesting to see how the experts weigh in on the Redfin. Since I had never heard of them I googled Redfin Shiner and read some info. Seems like they prefer to spawn in clear water - which is probably why you found them in the "crystal clear" creek.
I know many folks like the FHM as a boost forage just because they are slow swimming and easy to catch.
Seems like these Redfins don't get as large as Golden Shiners and GS are available all over the place (even in Northern California where we can't have Threadfins, Tilapia or even sterile grass carp).
I'm curious to hear what the experts have to say.
