Helene, thanks for the link to the thread you started on this question, I believe I missed that one in reading so many threads before getting my first paros. So, you and Peter and others have considered this question at length and even made some interesting observations. Hopefully you have found or will find a solution by trying different things. I know, when I said “maybe you could experiment”. I then thought about how much work that really takes, and time. So just take my comment lightly 🙂 Lawrence Kent sent me 7 tweediei young (9 weeks old) and already I can see at least two pairs in the mix under magnification. He thought they were not sexable, so maybe he just picked out 7 random fish (he has quite a lot of them) and if so, maybe this suggests a more balanced ratio in his offspring. I will ask him what water parameters he keeps and breeds his in.
