Just a as a bit of a side-comment: The two that I have are very distinct from one another, though caught at the same size in the same scoop of the dipnet.
One fish (the fish pictured) stays like you see it in the picture - fairly bold black stripe going along the body and extending onto the rostrum. This fish usually keeps a greyish head and rosy fins.
The second, stays a much more sandy-brassy color, with no stripe and a grey-purple head. It also has a very distinct dark marking just behind the opercle. This one is more camera shy, but I'll try to take a pic for comparison.

The one in my avatar was a male (a long time tank inhabitant that is sadly gone now after a long life)... he developed a very brassy look and kept a steel blue to real blue head all the time for the last several years of his life... and always had that dark line behind his head before his body.
I have a couple of new ones now... Alejandro and I caught em a little over a year ago down in middle georgia from a swampy, tannin stained habitat... at the time they were only 3 inch and looked only slightly different form the yellow fin shiners... now they are about the size of yours nad developing that nice brassy look, but still have some orangish color to their fins (thought that was a juvie trait?)... but no head color yet... I will have to check out the dark line on the side and see if it is going all the way to their nose...

I the temp has remained at 63-64 F all winter, so I contribute much of this coloration to the diet change. Like yours, Michael, mine are getting more and more brassy as they grow.

The fish that is more developed is smaller, with a much more blue head and can be seen in the background of the first pic. The fish that isn't camera shy, is larger, less developed, but with the head starting to show a bit of swelling.

I wouldn't put too much credit on the spirulina flakes just yet. The breeding cycles of many animals are affected by day length, not just temperature. For example, my chickens don't lay eggs in the winter, but they would if I put a light in the coop to extend daylight (or if they were particular breeds that are bred to lay in winter).
I don't know much about fish breeding, though, so take my thoughts as worth only about 1/2 cent.

BTW, read the label carefully when buying "spirilina flakes" from certain well known companies who put that on the label of their standard formula with a trace added way down the list. Get stuff where the spirilia is the first ingrediant.

I am with NativePlanter, and could not give the flakes the credit. I do think that the vegetable based diet mixed in helps. I must say that because of algae problems, I shortened photo period, and the tank is in the coldest part of the house. I think the cool temperatures has kept him in this condition. Such an enjoyable fish to keep. I did add some more circulation after a large water change, and he began to move a few of the larger sized gravel towards the front of the tank. But this only lasted for an afternoon and he quit soon after he began.
