Hello Peter,
Tks for your help!
I presume that the male eat the eggs. I don’t saw it but the eggs disappear in the nest and only the male keep them.
I have a breeding box to put the clutch in the adult fish tank but can I put the clutch in a little jar outside the tank with the water tank? If yes, need to change water in the jar?
What funghicides to use?
I’ll contact Hans Schellein to see if he has phoenicurus for sell.
I believe that the male eats only eggs in fact! It nourished not beside that! Every week he eats his eggs for the week to come…
Next clutch I take the eggs and I isolate them with a little leave of catappa in a little jar with parents tank water.
My female loves Mosquitos larvae!
All Paros love mosquito larvae, I breed mosquito larvae in the garden and Fütter my breeding pairs thus, brings humor and lots of eggs.
Yes try the eggs artificially hatch, but you do not do so many hopes. I sometimes can hatch individual larvae. The Paro men make it better:-)Yes, I know Bernd for the eggs but I want to see if they are fertilised or not.
And I want understand why the male eat them…
Just saw that you use ketapang leaves. Most of the Terminalia catappa leaves I have seen offered so far, are almost green dried, not really worth much. If you want the real deal stuff, order here:

you get 50 huge, premium quality leaves(naturaly fallen, well fermented leaves) for 13.50 bucks including shipment. This is what they really use in Asia.Good news, Hans will send me another male next week. I hope he will be better father with the clutch. I don’t try to isolate the eggs, no possibility now.
My actual male will go by a CIL french friend.
The quality of the water is the main problem if you try to hatch eggs without the father.
In nature, Paros live in running water. Additionally, the father makes a soft water-change-effect by his fins. This all is missing in a jar. There will be great problems of funghus and bacteria if you do not change the water. Mostly, this is not successful without picking out bad eggs in a daily turn und using funghicids and frequent (= daily) water changes.
Tks Peter,
I’ll change water in the jar every days with parents tank water.
I have a big serringue to make it.The eggs being yellow does not have to necessarilly mean that they are doomed already. A lot of different dyes are capable to penetrate the chorion and stain the eggs to some extend, it is only that unfertilized eggs will get stained much more. So there is still hope. If you use any type of organic dye like acriflavine or other dyes from that group, methylene blue and such stuff, it will always stain the eggs.
Hm that looks much worse then, they should be hatching at least soon, it also depends if you used the ketapang leave, how much tanins you managed to get to the water, sometimes to high of a concentration may harden the chorion to much and this can couse hatching problems. But I would assume that Paros should not have this problem most of the time. If you were able to tell if the eggs are developed, it would be much easier. If this is so, you could probably disrupt the chorions, but what you need to do it succesfully is to promote a growth of bacteria that would start to brake the chorions by adding some artificial fish food in there. Of course, once they hatch, you need to completely exchange the water, better is to do it twice (thats how we do that with killifish eggs that are developed but its hard to induce hatching for different reasons) and with paros where you get larve that are not freeswimming you would have to add fungicides again and hope. It would be highly risky, but if they are not to hatch anyways, may be some fry would survive. What you definitely need to know first is, if there are developed larvae in the eggs. But its really hard to say if this can work with such undeveloped larvae that Paros have. You could also try to scratch some eggs with some kind of fine paintbrush, that could probably disrupt the chorions too. I would probably experiment as much as I can if the eggs would probably not develope anyways without help. Good luck!
