Yaoshania pachychilus has been bred by Friedrich Bitter in 2014. Report in AMAZONAS September/Oktober.
As he has visited the origin river in south-china, he had some interesting news about to report. First question in keeping is, why they are so hard to keep in longer terms. Mine had all gone after three and a half year. Water-emperatures in that region is very low - down to 10. That means, they need very well oxygenated water and the temperatures over 21 - as in our tanks - are bad for keeping. I lost a lot of them in a summer with temperatures over 28.
Nobody can tell you, how old they become.
In Germany ther has been some effort to breed

They breed easily, but they don't last. Latest info is from the breeders above in 2015 (Gerhard Ott). As far I can see, there has not yet been a succesful breeding with F1.

*edit* I also have a sponge filter rated for 40 gallons
Ken- if you get to this side of the state, let me know and I'll hook you up.
Our Lake Michigan tap water in Holland/Zeeland is pretty good. I've bred over 170 species in it, including many cichlids, corydoras cats, livebearers, killis, native Michigan fish, and a couple generations of Senegal bichirs. I usually don't mess with it except for dechlorinator, or the occasional addition of RO water during a water change to simulate a rain storm. I'll add a chunk of limestone if I'm working with Tanganyikan cichlids, or leaves for added cover and for fry to graze on, but that's about it.
I do not get the spawning from the chenis I now have compared to years ago when my tanks were a few degrees cooler. Two or three years ago I ran across some Crossostoma lacustre and they did very well for me at first, even spawning at least once. But, I never saw any fry even though the eggs appear to have hatched in the gravel and the adults gradually died off. The tank was (and still is) a steady 75F up from 68-72F that is was when I first set it up and prior to me adding larger powerheads. These temps are not a problem for Sewellia,however, since I get spawns all the time.
It would be great to understand your routine and setup to breed. You touch on some items but could you each please share details on your own tank setup, tank layout, water parameters, water change routine, fish/plants/etc kept with them, foods used/frequency fed, keeping eggs and fry alive and anything you think are key points to be successful. I know it’s asking a lot to take the time to write that all up but you two seem to be only ones in my research besides one other person to actually breed them. This would be much appreciated if you could. Glad to share my personal email if you want to connect offline.
