To be honest when I had a group of angelfish they were full of personality. Bolivian rams have lots of character for their size.To be honest most cichlids will show this so called character.
Acaras are another group that show this trait.
All Cryptoheros species do.
Infact I think all c/a cichlids have character. Most of it stems from their breeding strategy and their need for territory rather than actual character.
