I recently got three dozen from Tropical Lagoon for about $3. I was expecting about two thirds of them to die off, but they all survived. I quarantined them in a yard tub with lots of tannins, then brought them inside and treated them with a de worming agent. They're still in quarantine.
The wild types in the photoshoot died not long after, from skinny disease (that's why I used the de worming agent on the new ones.)
I have some fry from the spawn in the photoshoot, which I'm growing out now, with some rosy barbs and white clouds in my show tank. All wildtype.
so how much are your feeders?
