Hey Guys!

I am quite new to cichlid keeping.This is my first post.

So recently I bought a tank which came with a 13cm Pearl Cichlid.  In the tank at the moment there is a 7-10cm ghost knife, a few Rasbora's, a bristlenose catfish and a couple of small shark thingys. Theres alot of tank room so I want to add more in.

The pearl cichlid is aggressive but fine with them.

I tried introducing two smaller cichlids but overnight he killed out and I got the other one out before he could kill it as well. 

Would a 10-15cm Red Devil be fine with him? and would it attack the ghost knife? 

Also someone is willing to sell me a 20cm pearl cichlid. Would that be fine with my smaller guy? and would it be fine with the ghost knife?

Could I put discus or angels in there or would the pearl be aggressive to them? I was thinking maybe he is just aggressive to other cichlids maybe.

Any help is greatly appreciated
