I thought I heard that ORA or some place is commercially raising peppermints. Just checked the ORA site though (
www.orafarm.com) and they don't mention it, so maybe not.
Basically, it (raising the fry to adulthood) doesn't happen by accident in our tanks at home unfortunately. Like I said in another post though, "their sacrifice is not in vain" because they are an easy supply of zooplanktonic foods you could ask for in your tank.
