If your interested in orher fish besides cichlids i would look into polypterus (bichirs)
For me keeping large to med cichlids was/is a pain. It has worked for others so im not trying to discourage you. I keep a group of polypterus in a 150 (badically the same as your tank) with the pearsei and i have 0 issues.
