Erica Weiser asked me to post here on my experiences with Notropis chromosus.
Here is a video of some two week old fry that I have recently bred:
Any questions please ask.

What foods did you feed the parents?
Once free swimming they are very small, mine get paramecium for about a week, I add in microworm after a few days free swimming and after about a week I also add in live BBS twice a day, three or four times a day if I am not at work, I stop the paramecium once they are eating BBS. After about 2-3 weeks they start getting live grindal worm and after about 6-8 weeks they just get exactly the same as the adults. The fry get 90%+ water changes twice a day.The fry?
They are kept at about 21C generally. When I am trying to get them to spawn they get plenty food and I do 50-60% eater changes every day with cold water straight from my HMA water filter, this drops the temperature to about 12-15C until the temperature in the fish room brings it back to about 21C. Often if the fish are well conditioned they will go into spawning colours within a day or two, but it can take weeks sometimes. You will not miss it when they are in spawning colours, they are absolutely mind blowing. I ahve a video somewhere which I will upload.What temperatures did you use to trigger the parents to spawn and for how long?
I dont have a picture of the breeding tank but its not worth showing anyway. Its a 2x1x1 bare tank with a sponge filter with vigorous aeration - that's it for maintenance. When I want to breed them I start the water changes, add a 500ml takeaway container filled to the top with rounded pebbles (about 3/4 to 1inch diameter) and a pwer head with venturi blowing aerated water towards, but not directly at the container, this usually gets them going crazy, they lay their eggs in there and only there.Do you have a picture of the breeding tank?
