Thanks for the reply. I will try it out if i end up with fry this round.
I just took the parents out of the new attempt of a breeding tank (mesh bottom with a mop and some random stem plants) the ground is a bit dirty from pulling out them steams from other tanks so its hard to tell if their are eggs or not (they were in there foe a week so i hope so).. i put 1m/1f adult CPDs into a shrimp tank to test and see if they mate int here or not and the the other females back into the main communal tank.. so hopefully some fry pop up in a few days
