You’re very welcome, sir!
Transferring the remaining young to a larger rearing tank may be helpful, Roy. It will provide a little more stability and a little bigger margin for error, and certainly could help make things a bit more sanitary, but it will also mean that the daily water changes will need to be correspondingly larger in order to replace the same percentage of water during maintenance.
And, the larger volume of water will also make it more difficult to maintain an adequate feeding density of the newly hatched brine shrimp (Artemia nauplii). It’s important to maintain a good feeding density so that the fry do not have to waste energy chasing after live prey that is more widely dispersed, so you’ll need to hatch out even more brine shrimp in order to maintain the same feeding density in the larger rearing tank that the newborns were accustomed to in the smaller nursery tank.
So those are a couple of factors to keep in mind when deciding how big you might want to make the rearing tank(s), Roy. Don’t go overboard because the larger rearing tank can quickly reach a point of diminishing returns and eventually becomes counterproductive for the home hobbyist with limited time and resources.
