Breeding Black Lancer catfish.

[Fishy-Botany]

I have been able to aquire 4 juvenile Bagrichthys macracanthus. Iam hoping to have both sexes present.
I would like any help on finding out what it takes to breed these guys or breeding conditions of related species that I might try on the black lancers.
So far I know that at least as juveniles they can cohabit together, with an obvious pecking order that is inforced with just circling each other.
I have two of them in a 40 breeder, one in a 30 gallon and one in another 40 breeder.
Thanks for reading.
I have a sister thread on planetcatfish

Is it known if there were any successful attempts before?

So far I can't find any previous successful attempts.
There is little info on breeding, so far I've found good info on sexing but that's it.
My best guess so far is that I'd need a 180 or 210 sized tank and caves made of driftwood and rock, Three per lancer probably.

I'd probably have to simulate a dry season and then a monsoon season also.
