Helene, nice photos! (Hope I will see some of these nice mini-nagyi in my tank too, one day)
For me it’s very interesting that it goes that well – so many fish of one species in one tank, and they’re breeding! What you tell doesn’t sound as if there was much aggression?
Concerning the Boraras ………… I think they are real “fry-catchers”. I have B. maculatus in my Badis kanabos tank – and I had a lot of fry when the pair was alone. Since I put the Boraras in that tank, there are only very few fry – although the male Badis is breeding …. and breeding …. and breeding …. I am not worried about this, because I still have more fry of Badis kanabos than interested aquarists …. But never trust the Boraras ……..
