That’s all very nice and fine, flowing water, just as in the native streams and peat bogs of our Parosphromenus fish.
But what is with the very young fry? I should ask especially Lisbeth, but the others too. Of course you can arrange a water movement, more or less, but isn’t it mainly thought from the perspective of the adult fish? They may breed very well, but do the young survive? In my opinion this will only work with bubble filters.
In my small tanks it’s impossible to copy your technical arrangements. But sometimes I have 30 or even 50 young growing up there.
Lisbeth, Helene, Bennie: If your fish “look so happy” with all that, how do you recognize that? I cannot imagine by the number of the young…
