Jags are also very interactive. Cubans too they also both look similar to the Hatiensis. Bigger personable fish would have to be solo in your tank. There's also smaller options. Acara's have a lot of personality. When I began hand feeding the acara's actually were the first to get over their fear of me. You could get a few of those. Or get an electric catfish. (my personal favorite) Hands down the most fearless fish I've had access to. Definitely a solo fish. Sometimes mine likes to swim and rest in my hand he bites me lightly when I try to take my hand out. Other days if it wants alone time it will let me know by shocking, biting hard (he has no teeth) and ramming. Very exciting fish I must say.
