Over the years I've seen acroporas under multiple names, some of them are more a family classification than a name. I've run across milli, tenuis, stag, tort, and digiti. Are there others? I can tell a milli now when I see one, but as for the rest, I'm totally in the dark. It would be great if I could better understand this as there are some I like and others that I'm really not fond of. Any guidance would be very appreciated!
