Any guesses on these fry?

*They're captive bred, and one of the 'easier' and more readily bred species of shiner.
*They are beautiful as juveniles, and especially as adults--even not when colored up.
*These are ~2 months old.
*They would definitely be Roll Tide fans.

Which one's Bear, and which one's Nick?

I can think of no elephant shiners nor crimson tide minnows.
Rainbow / Chrosomus still seems most likely to me.
Mr. Redline tattoo needs to provide another round of clues and a close up photo of one of these mystery babys. Half an eye of red would help, which is a clue to you.

I luckily happened to see several individuals of a population of ~18 adults in a 120 gallon display tank spawning between some large rocks (as opposed to over a chub nest as they do in the wild). I gravel washed over that area and sucked up most of the eggs into a 5 gallon bucket. They were kept on constant air and received a 50% w/c daily. A few weeks after hatching, I moved them into a 5 gallon tank. A sponge filter was added but daily 50% w/c continued. As they grew, they moved into a 10 gallon, and finally a 40 breeder from where the pictures were taken. I am only aware of 2 that have died, both within the first few weeks after they became free swimming.
I made a post a few years back about rearing the fry as I was having some difficulties at that time. Their numbers just kept decreasing from week to week. A few had suggested keeping a light source on 24/7. THAT seems to have been the trick. Even since they were eggs, a small, 18" fluorescent light has been kept over their tank(s). They are thriving and eating microworms and artemia nauplii 2x daily. I'm starting to introduce new foods at this time.
Thanks to all who participated. More to follow...

Bright powder blue and hot magenta are the colors vivid to my memory.
Klaus S taught me to look at their eye, one half of it will be red. A diagnostic trait.
Keep us updated on their growth with photos.
A good experience for you!

Hints:
*It might have vertical stripes on occasion, but they are not a defining characteristic.
*This fellow is not 'truly' a member of the family we commonly refer to them as.
*Ben Stein might offer it 'Clear Eyes' for its (bright), red eyes.
*When it first hatched, it was not able to eat artemia nauplii (for a few weeks, anyways).

Hints:
*Most of you are familiar with members of the same family that are abundant east of the Mississippi. This one is found way out west.
*It is a Federally Threatened species.
*Only found in the Rio Yaqui drainage of Arizona and Mexico.

The last species will be quite the challenge. The only credit I can take is that the pictures are mine, (I did not breed this species, a co-worker did). None the less I will see if any of you can figure this one out.
Hints:
*It is a cold-water, marine species.
*This is a fairly common species, ranging from Alaska to Southern California.
*In their larval form (pictured) they are pelagic like most marine fish. They use their large pectoral and dorsal fins to navigate throughout the water column. As adults, they are demersal.
