Orchid dottybacks are aquacultured by ORA so they are fairly easy to raise with the right food. My Banggai cardinals have babies fairly regularly...fun to watch the tiny cardinals swim out of the males mouth. They are a bit easier as they come out large enough to eat newly hatched brine, so you don't have to go they whole rottifer stage. My 30 year old clowns still spawn about every 15 days. I'd love to try to catch one one of the spawns and try to raise them. I've also had numerous male pipefish give birth. The babies look like tiny pieces of thread. Never been able to get them past a couple days, but we will be setting up a live feed station soon to try to raise some.
