Patrick, thank you for your short diary. In the moment I cannot detect any bad mistake that you made. The development of the single stages seems to be fully correct. I can see only two possible causes:
1. either too much change with waters not fully identical with the original tank-water,
2. or fed too much Artemia with an overload of organical waste to the water
I recommend you the following:
3. If your pair is a good pair, it will breed again soon. If your tank is full of plants, leave the next fry where they are with their parents. Often, some or many young will survive (“extensive breeding”).
4. If your tank is not full of plants, remove the adult fish at that stage whre you removed the young this time. If you have a similar tank, the adult pair will breed again when you put it in there. Mostly, Parosphromenus breed soon after a good feed, a water change, or transferred in a new tank.
5. Feed infusoria a bit longer and Artemia a week later.
Good luck!
