I really like the sheepshead minnows, but haven't had any luck keeping them in pure fresh water, even when I collected them in pure fresh water. I'm an experienced aquarist and have kept a few difficult species, but I've tried twice and not managed to keep the "easy" sheepsheads alive. Willing to try brackish, but not excited about it.
I'd like to try a 4' river (flowing) tank, mimicking a "Tennessee River Shiners & Dace" tank at the Denver zoo. I don't live in Denver (or Tennessee), so I'm looking for a Houston native fish that will work well in this type of tank.
I can get sailfin mollies, sheepshead minnows, or red shiners fairly easily. None of those have the torpedo shape of the Tennessee fish. Would any of those be good with current? Other suggestions?
Thank you.
