Yeah but im looking to the Oscar...If you dont have the o already there a lots of other cool cichlids that would be fine in a 75. Yellow or blue acara (metae/pulcher) and some cryptoheros (sajica, hrp, nanolutes) could be cool
In my experience lots of smaller cichlids like those mentioned above have just as much of this personality you seek.
If you want multiple cichlids is it fair to cram them in a small tank?
I think the whole "oscars have the best/most personality" is blown out of proportion.
