I have 2 Pearsei, just over 2 years old. Largest around 12" (30cm) in my 210 gal (around 800 liters) with different caliber cichlids and non cichlid species.
This is the first time I own Pearsei, when I did my initial research before buying them as juvenile, most information I found is they are very peaceful fish. And it was true for almost 2 years, when even much smaller Thor Meeki flaring to them and my large trio Heros Efasciatus chase larger Pearsei very often.Until they (Pearsei) start mature. Today everything change and they in charge of 210 gal tank, dominate even 9.5" male N.Tetracanthus.
Still, Pearsei are not nasty fish, and leave alone much smaller Thor Meeki and most my tank inhabitans, who probobly is not seeing as a treat a compitition for food and territoty.
So, to answer your question about Pearsei making good tankmate with Rostratus, I am not sure, I wouldn't risk in the long ran, it may go both way, since A.Rostratus medium size cichlid and may be seeing as a treat and they wouldn't be able to hold their own against much bigger and powerful fish like Pearsei.
As for Bocourti I didn't keep this fish yet, so no help here.
Here you may be interesting, my Pearsei thread, I start couple years ago, fish development, thoughts, etc..
