@Helene: yes, I found the egg – clusters and I had read before the thread! I´ve taken them out to try to find the moment when the larves come out to feed them as very small larves!
the for me unknown animals I don´t dare to feed at the moment, the look for me a bit dangerous 😉 I will look in the www for daphnia information!
@Deepin peat: you have a nice humorous way! 😉
