Both vendors in our group buy have them (Cichlids of the Americas and Mike's Cichlids).
I've bred them a few times and just lost the male of my pair. Festaedan's getting the female and I think a male from the group buy.
I've sold a couple of more adult, breeding pairs to folks in the area in the past couple of years, so maybe they're around.
It's unfortunate that the only chanchitos in the hobby are Red Ceibals (and oblongums). While they're great fish, there are dozens of other varieties... many of which are cooler (in my opinion)
