Just because the fish is raised in captivity doesn't mean it changes behavior... You can't put them in community tanks and expect them to compete. Like great they eat prepared foods like mysis, brine, or pellets but they are still going to be easily intimidated and people need to plan the tank for them, or have a huge tank where they can forage.
What is good about the captive raised fish is that the idea is hopefully you aren't getting an extremely emaciated fish that has just traveled half way around the world, that has no taste for food at all, even if the pods are practically swimming in its mouth.
I saw the ones at MACNA they had on display and they had a bunch in a small tank of their own and turned the pumps off to feed and none of them went crazy for prepared foods, so they are still difficult to keep and you gotta know what you are getting into.
