Occasionally see Holacanthus hybrids as well.
And since most hybrids can't reproduce it isn't exactly evolution happening

Kind of a dead end although they may exhibit hybrid vigour.
This is a great thing for aquacultured food fish (something that's been done for years with corn).
I've never looked into the hybridization of other oceanic critters, I like the fish and babes concept though
I'm not even gonna touch how all this involves evolutionary genetics and conservation genetics
