Just wanted to share these two pictures. The wild male I have continues his “out of the cave” strategy. What we can learn from the pictures that are 10 days apart is that the eggs have quite a big perivitelline space which seems like they swell up after deposition similarly to for example Nannostomus eggs. They are almost that big too. The larvae from the first clutch are already in the tank and I will try to make sharp pictures of the new one every day when I am home.
Thanks Rafael 🙂

I have 10 young specimens growing already, not sure if the parents continue their reproduction, I gave them a sligthly bigger tank with some plants and leaves, so not that much control anymore. In case I do not spot any fry within reasonable period, I will switch back to the controled aproach and remove the fry before freeswimming.
Thank you very much for the nice words Peter. I apologize for my late reply. The fry is still growing, now 7 weeks old and the males are starting to show dark bands on the fins. I have at least two friends who will jump after the fry and I hope to get more of course. Even the second female that looked pretty weak when they got to me recovered well, so I hope they will breed again. All the adults seem to be in good condition a there is plenty of mosquitoes around.
there are at least ten of them. Had some losses when I was away from home but they seem to eat fine and grow well…
Hello Peter,
we have a friend, killifish breeder, in Indonesia who is able to obtain wild caught bettas mostly. I think the fish come from some small scale collectors and fish like that are not traded in big numbers, there is quite a market with such fish between the enthusiasts. His friends are sometimes able to bring such fish to Europe. I had no space to taky any fish from him this time, so I did not even check what was available. But I think two weeks ago or so, my friend told me that he has a group of parvulus, that he took from him and he wanted to give me a pair. Of course I had to make space for such fish, so I agreed, but before we were able to arrange the handover, he lost most of the parvulus and I got what he had left, two females and a male. So since that time, the fish recovered nicely under heavy feeding and with heavy water changes.
What is important for your question is that the Indonesian friend told me they currently know about three locations where parvulus live. The fish that I have come from Bukit Batu near Palangkaraya , Kalimantan Tengah.when you expand the picture, you can see a dark line dividing the second closest egg. This is an embryo forming already…
Thanks Josh,
there are already larvae on the bark, I guess they have spawned on Friday. I am quite sure the water should be ok, it is all up on the male now. He seems to be doing ok so far, wild fish are usually good parents, so I hope for the best. On the other hand, I think the larvae are close to the point when I could remove even the male.
will keep you posted 😉
Do you recall some of the species Josh? I remember Peter mentioning some, but I was unable to find the thread. I would like to give it a try and need to know what species to look for. Thanks for any help 🙂
The more I look at it I wonder if they could be pahuensis. Could someone experienced look at it? The fish have typical “shop” coloration, I think I may have overestimated myself 🙂
