Hallo again!
(thank you for you private answer, too)
I tried once, but here they are difficult too find and to keep, and I don’t see a great advantage /artemias, but for the little size perhaps. For young fishes, I have also a sort of “big” freshwater infusiora Jürgen Ende in Germany gives me, which is easy to keep and to breed, with very much animals you can see with the naked eye in a little bottle and sometimes develop later in the tank. That can I send you, too.
