I own a trio of C. weitzmani, which is a cory they once thought was extinct. In 2004, while cutting roads in Peru, they were discovered again. The first ones exported sold in Japan for the equivalent of over $1000 (USD) Since then, more have been taken out and, of course, the price has come down.
However, now they are doing gold mining in that area and it is expected that the stream where they come from will be polluted by the waste products of that industry. There is a very real chance that they could become extinct for real this time.
Cory lovers are trying to breed it to keep it going, if only in captivity. I know of once case where they did spawn, but only a handful hatched. With luck, they will grow into adults. This does show that it's going to be possible to breed them in captivity and the species can continue.
