Titus my man, guess what im picking up on my tomorrow morning
1000 mile round trip for a pair of H. Notatus... if they are indeed Notatus. REALLY HAVING DOUBTS, especially now, since i've just ask about their markings, and apparently, they dont show any black on the flanks.
I'd personally go for Inirida from your list. I'm yet to see and adult male.
As for the efasciatus, they are the same species as appendiculatus. Good one to watch out for.
Officially, there are only 2 members of the heros family. H. efasciatus and H. Severus.
Everything else, for the time being, is a regional mutation

Remember that when paying.
efasciatus = appendiculatus = notatus (sometimes, as it has come to describe a regional variant, which is highly sort after )
All names used to describe the same fish.
I'm sure Jeff himself will burst from his fish house and prove me MASSIVELY wrong, but thats how i understand it from teachings from fellow Sev HEads in england.
Best of luck
