Breeding Question

[Sea Witch]

I know that there are several marine (aquarium) fish that have been captive bred and I'm familiar with the breeders' registry, etc.

My question is are there any fish or crabs or shrimp that have reproduced in a reef aquarium without the help (or interference) of the human? i.e. no separate breeder tanks or raising fry with special foods etc. I mean young that reached adulthood or at least beyond the juvenile stage......?
