I actually had a recent discussion with J. Ekstrom on the subject, as I was looking for advice on how to work out a possible L-128 breeding setup... apparently, there have been no actual DOCUMENTED occurences of spawns, while several (or rather, one or two notorious) plec "breeders", which names I currently keep in mind, have claimed to have spawned this species, with no evidence of fry nor clutch. I have been around plecs for all of this and half of the last decade and to my understanding, despite the distinct variants of L-200 having been known since the endowment of the number, neither have been documented to have spawned, save in the last 3 or so years. If you do end up obtaining some spawning pics from you and your friend, you would blow much of the loricariidae community out of the water.
