ive had a fh before and i always want to try something different ... i know there not american but im reading buttekoferi might also be very high in the list
you answered your own question
however, every individual fish will vary on their personality in terms of being a glass banger and chasing your finger. you might get a shy dovii who will be scared of you or one that will want to kill you...
Butti is a great choice as most are crazy aggressive...you can also try a red devil, jag, hait (my choice), or some umbee's are glass bangers but usually not until they are bigger
