The largest hurdle has been conquered (successfully breeding them in captivity)! I'm SO glad to see significant advances breeding many common marine fish.
Here's the list of all of the ones I can think of off of the top of my head. Some are much farther along than others, but it would be cool to get a list going:
Regal Tangs
Yellow Tangs
Bangaii Cardinals
Pajama Cardinals
Oscellaris Clownfish
Flame Angels (Hawaiian)
Coral Beauty Angels
Multicolor Angels
Scribbled Angels
Bellus Angels
Mandarin Dragonette
Several Dottybacks
Several Blennies
Several Gobies
Filefish
Azure Damselfish
