you will need larger than a 1 gal, I would go with at least a 10g, and then you need to have very light filtration so the young shrip do not get sucked up. You may even need to move the adults out, but I am not sure on that. Last the feeding will be harder than phyto, that may work as they get bigger, but I am sure you would need something smaller than that. There are people on this site that know much more than I do about this. I was able to get them to breed, but never past the first few hours of life for the babies.
