Also, Pellegrini are very different from red humps or steindys. From what I've seen online, and according to Jeff Rapps, they are one of the more docile geos.
Pellegrini hogging my tank - help with aggression

This would surprise me greatly considering they were considered synonymous at one point. Steindachneri, pellengrini, and crassilabrus all fall under the common name "red humps" as well.
I've had pellegrini a few times never found them really aggressive, I would say out of the group Steindachneri was more aggressive I've keep them with central and had no problem holding their own (the males), I remember a male I had would spar with a black belt... I'm growing out some crassilabrus now I've found this particular group to be very slow growing..
It was "normal" before you added a new fish and changed decor.
By changing things you allowed for an entirely new hierarchy to form, where the 8 inch red hump ended up alpha.
And although you may think 90gal is sufficient for your fish, they may not think so.
If it was a 90gal 6ft tank, the footprint may have worked, but if its a normal tall 90, the footprint may be too small for that many substrate dwelling Geo's to share.
I agree with new world that the red hump group are more like Central Americans, than the less aggressive/passive S American Geophagini tribe species. Most Geo's wouldn't even contemplate sparing with a black belt. I have also kept the red hump group with Central American, that would easily destroy some of the more passive Geo types.

Plan on purchase one Pellegrini for my community tank Oscar, GT, jack Dempsey and chocolate cichlid could that work and would I need to purchase more then one Pellegrini??
The Geo's from west of the Andes (pellegrini, steindachneri, and crassilabrus) are on an entirely different aggression plane from Geo's from east of the Andes. Where a standard 90 might be OK from eastern Geo's, a 90 for those from the west is often not nearly enough.
I personally would not keep western Geo's with those from the east, because of their different temperament.
I don't think your pellegrini is being odd at all, it is doing what I would expect from Geo's of that geographic area.
