Hi Bernd, why do you put the fry in tap water? Our Black Forest tap water has ec 250 …. that sounds that would be nearly ideal water for rising young Paros ?????
Hi A.J. , that “getting used to the new water” we know with shrimps or with our Paros from trade … sometimes they have an ec of 800 …. (salt added to the water …).
I take then a thin air hose, fill it with water like when I do water change with a bigger one, top end in the prepared water, upper end down in the “old” water with the animals, and check the flow with a clamp, so that drop per drop comes the new water to the animals and from time to time I remove a cup of the “old”water.
