Hello Bernd,
thanks for your method. I forget the bredding box also.
I’ve youngs Paros tweediei and youngs spec. Dua in their parents tanks. Youngs tweediei eat already brine shrimp with their parents, I’ve a lot of Ceratopteris cornuta in my Paros tanks and the youngs stay in.
I need to find others tanks to keep Paros youngs.
