I currently have 6 Placidochromis Phenochilus in a 55 gallon tank. I was wondering what else could I house with them? If need be I could move them to a 75 gallon if thats what I need to do to be able to add to them. Bring on the suggestions.

They will definitely outgrow the 55 in short order. I would move them to the 75 regardless and in a couple of years (depending how much you feed) odds are you won't be happy with them in a 75 tank either. I have found once the haps get beyond 7in they really look cramped in a 4ft tank to me.

My experience is they are peaceful and large so you can house most any haps/peacocks with them.

Aulonocara sp. "Stuartgranti Maleri" or one of the other predominantly yellow peacocks would be a great place to start IMO.

Good Luck.
