Yea, it makes it tough to know what you're getting when you want fish that are not grown commercially. Like you said, they come from the wild so you are throwing the dice. I got lucky with where I'm getting my RRs. It's a pet shop and they quarantine their feeder RRs, guppies and goldfish for 30 days before they will sell them to make sure their is not something hinky with the fish.
