So they can fire up and spawn without other minnow's nest [stoneroller, chubs,
etc.]? Hmm... Anything you think trigger their spawning? Just being kept well
and healty, temperature, light, etc? Also, in the book Freshwater fishes of
Virginia it is written that saffron shiner spawned in water of 16.1 - 30 "C. Is
this really true? Isn;t it that saffron live in blue ridge which streams are
supposed to be pretty cold most of the year?

I remembered watching a young Tangerine in Casper's tank last year. While rainbow
darter in more free-space tank breathed heavily, the tangerine in the other fish
[minnows] - filled tank breathed normally and competed well. Maybe they do better
than other darters at warmer temperature? Since I had seen a full color monster
in Tennessee Aquarium darter tank I knew they can color up fine in cold tank but
what about in warmer tank?

So not all KY arrow spilotum? Which area in KY that real sagitta live in? I
think arrow are listed either as special concern or something like potential or
proposed for threatened [something like that] in TN. What is special concern/
proposed status regarding to collecting and keeping? Are these status simply mean
the fish with such status cannot be collected anyway?
