Cichlid possibilities

[GoldenPlecTony]

Hello people,

I have a 90L tank and just wanted to know what species of cichlid I could home and how many? I want these as a centerpiece fish (Hopefully).

I just want to know roughly what I can home so I can start looking into them in more detail.

Cheers

Or any sort of oddball fish. I dont mind if they need to be kept alone etc. I would preferably like 1 I could feed that is semi agressive to agressive.
