Over 2000 species and you narrowed it down to 5? Is this for personal stocking advice? Out of those choiced I have only kept two. The oscar and RD (or Midas) and they are equally intelligent and interactive.
I have kept 4 out of the 5 mentioned and i would have to say the Oscar has the most "intelligence" and "personality". Its very subjective of course , its all based on personal observation .
One of my Oscars is smart enough to recognize which container the Krill is in. When I pick up the pellet container, it gets his attention and he swims to the front of the aquarium. If I pick up the krill container he rushes to the front and tries to swim through the glass.
So he's smart enough to recognize the krill container, but too dumb to ever realize he can't swim through glass.
