These were offered up a little while ago... gone now, sound rare to the hobby... Nematobrycon lacortei

keeping an eye out if they come around again...



don't know how good a source this is, but it came up 1st in my search...

and my old stand by...

They are what I call once a year tetras - they show up, but you are lucky to find one import per annum. So they aren't rare, but they are uncommon.
I also find when they are listed, what arrives are often not lacortei. They're often the more available palmeri.

Found them on Dan's Fish but.... out of stock.
