Breeding them in captivity isn't going to replace the ones that are missing from their wild habitat. Unless a specific breeding program is set up to replenish the depleted stocks then it could take decades for them to reach the numbers there were at before the population explosion.
While it's good to hear people want to breed them, and that they are able to be captive bred, the bigger picture means that it should really have been researched before they were taken from the wild. I don't deny wildcaught fish are a necessity in the aquarium trade, but I do think that a little bit of forward planning might have been able to stop what is essentially a very sad tale.
