Hello, I also thought about this kind of solution.. but I would like to do “two tanks in one”. One 40 cm tank will be splitted on two parts using the acrylic glass. In one part I will set up paro pair with all leaves, java moss, cave..and the second part I will manage in the same way but without paros. After a spawn, I will pull up the acrylic glass and gently move the female to second part (she will swimm to it alone without a any net and so on…) Then after a few days (when the fry will hatched) I will remove the male… It is like having two tanks but without any stressed catching fishes by net after spawn…
And one more thing – I have the same experience with P.nagyi – only 3 pcs of fry I had from one pair when I left them in one tank…(extensive breeding )
To compare – P.linkei I had about 30 fry from one tank (extensive breeding method)
P.cf.bintan “Blue Line” – 1 fry…:) – that’s why intensive method is needed..:)
Best regards
