Feed flake food, soft-moist krill, frozen brine shrimp, freeze-dried blood worms, ...
p.s. Try keeping your breeders at a constant 66F. It is possible to keep them partially colored-up for months.

Here's another rainbow shiner enthusiast, in England ! Great to hear yours have bred as mine have just spawned too! They are very rare here and I believe mine could be the first spawning in the UK. The fry (about 80) are 9 days old from spawning and just free-swimming. I've just started feeding my usual fry-mix of green water, infusoria and boiled egg yolk suspension. On what did you feed yours at that size?
I would have thought that even at 1cm your youngsters would now take just about anything. Try them on crushed flake as main diet, perhaps?
Aren't the adults just stunning, stunning creatures? For me they are the world's most beautiful fish, sometimes almost beyond belief, a cyprinid from another planet!! I'm totally bewitched by them, they are going to take the aquatic world by storm in England.

Thanks for the food & temperature advise.
Nice to hear there are other enthusiast, mine are 1.5 centimeter already, 30 or 40 of them, I feed them with green water too, brine schrimp,and the egg/milk, the instant food for egglayers you can buy in the shop, furtheron I breed my own Daphnia, and the smallest Daphnia I give to the young.
Today I refreshed 100 liters water from their tank, it cooled the tank to 22 C , and the water is clean again.
The fish are rare indeed , I know only one shop in the Netherlands in Amsterdam were you can buy them were they got them now and than. Concerning the temperature, I have not much influence on that, the tanks are in un unheated shed, in winter the temp was about 2 - 5 C they survived this very well and now the tanks are warm 24 C and there is nothing for the moment I can change that. I try to keep them at 18 C, it is better for the fish I know when you keep them to hot they age quick. With these fishes I am very careful, may-be I can cool the tanks with some ice or so when it is getting over 25 C this weekend.
I learned when I checked the internet someone in Germany is breeding them too, but still it is not a popular fish with the public.
There are still few people breeding and keeping these fishes in the Netherlands probably I am the only one too, I know there is in Belgium also a guy breeding them.
There are more interesting minnows, like Notropsis lutipinnis, stunning yellow fish when breeding.... . but very very difficult to get in Europe.
For now I enjoy my shiners, N. chrosomus and hoping the other tank will also give me some young N. chrosomus fish. I have to dig a pond, this autumn to raise all the young fish when I am lucky... - The Notropsis lutrensis has young too and the Rhodeus ocellatus as well, we will see.I enjoy myself a lot being busy with it, for me the most important thing,CM

and when they start to spawn you cannot believe your eyes,stunning beautiful.

I've also seen videos of the Yellowfin Shiner, Notropis lutipinnis. Crazily beautiful! Do you know of anyone keeping them in Europe?
I've seen a German website that has videos of home-bred Sailfin shiner, Pteranotropis hypselopterus. Wish I could obtain some of those as well.
I was on holiday last year in the Nederlands near the beautiful town of Leiden and visited Aquarium Romberg in Delft and Heems in Heemstede. Very good shops I thought, especially Heems. Do you know them?

Good to hear these fishes can cope with high temps as well, as I got 26 C today, and I cooled them one hour ago with ice, to 20.5 C this afternoon.
No i do not know anyone who can help us for N. lutipinnis or the other species you mentioned, unfortunately, which are very very nice as well.I made already a try last winter to import fishes from USA but the costs of the import permits, veterinary reports, and transportcosts made it to expansive for me and the shopkeeper who tried to help me to import these fishes. Unfortunately,
I have been to the shop in Delft but not Heems, I should visit this shop as well. I did visit a shop in Amsterdam, molliensia, a good shop, but the owner retiered, and the shop is now closed, I am visiting nowadays a shop in Purmerend, were we live and a shop in Amsterdam, Tropica, were i bought the rainbow - shiners. Aktually I was asking for Elassoma evergladei, but the shopowner told me he had something very special, and you know what he said. So until now no Elassoma's, but shiners.. . I must admit when I heard what I had to pay for these fishes, i had to think again, because i also could have decided to buy ad dog with family history for that. But i did not regret a day i bought them, and when it rains, i don't have to go out... . CM

Thanks for you reply with the food & temperature advise, I already brought temperature for the breeders down from 26 Celsus with ice, close to 68.9 Fahrenheid, 20.5 Celsius,temps did rise slowly and this morning I measured 69.8 F , 21 C in,which I brought down to 68 F, 20 C with available new ice. As it looks now we passed the peak from this high temps in the Netherlands already. It should be possible to bring the temps down to 66 F this afternoon when water is froozen to solid ice. Yesterday it was 30 Celsius in our garden and we live in a coastal area, close to Amsterdam, inland in the Netherlands temps were even higher. In my shed with my tanks with the fishes it was 35 C and the others tanks were 26 Celsius - 78.8 Fahrenheid yesterday afternoon.
Concerning the food, I have started to feed them as you advised already, and I noticed they can eate a lot more than brine-shrimp. However, there are huge size differences between the young fish, some of them are close to 1,5 - 2 centimeter others hardly 1 centimeter, and the last mentioned still need their brine-shrimp diet, and other small creatures.

I will take notice on that, and it is what Philip said, with these cooler temperatures the breeders keep their colours, they are so nice it is all worth the efford. In a few days dutch weather forecast is expecting hot weather again, The young I dont cool, and the are growing rapid now, lots of them are close to 2 centimeter, and gorge whole day small daphnia, moskietolarvae, and smaller critters, showing even their first colours, nice to see.

My rainbow shiners spawn even at 27 C, as long as they are well fed and given frequent water changes. The coldest they ever get in winter in my house is about 20 C. In summer their aquarium can sometimes get up to 30 C and they seem to do OK.
You should get some dechlorinator and treat some tapwater to freeze next time.

Or you can freeze water in plastic bottles or bags, and float them in your tank until they're no longer cold. The temperature lowering is more gradual that way (less shock), and no worries about chlorine. Just trade the bags or bottles back and forth between your freezer and aquarium as needed.
That works well, too. The last time I did this, I froze dechlorinated water in plastic containers to make great big ice cubes.
