Thanks for your reply Peter.
I noticed after my post that I forgot to mention the option with just let it run like it is
but with a reason.
For the tanksetup I got inspired by the “Methodical alternatives” thread. So I stripped
down the interior on only peat fibres on the ground, one root with Java fern on it,some Ceratopteris drifting on the surface, spongefilter and a broken flowerpot as cave.
It´s far away from a heavy planted tank but with adding some leaves I could offer some hiding space for the fry.
After I noticed the nest in the tank I did some research and read often that it´s possible that
parents eat the fry or that it`s often not very successfull to leave them together, especially with such a setup. That was the reason for my concern and leaded to the idea of moving one party.
But I guess I´ll go for adding the leaves and let it run. Maybe try to put a small amount of fry into a seperate box to get a feeling for raising them intensive. Assuming all goes well with the fry of course.
