Maybe that's a good thing. Your pearsei may be the most "personablel"of all the cichlids you've gotten from Don. They're VERY friendly, and as others have said, can be called "true aquatic pets." Having kept both, IMO they tend to be more friendly than Oscars (even BAD Oscars - couldn't resist) and perhaps the most "peaceful" large (eventually reaching maybe 12"?) fish you've got.
When I first kept pearsei, having aquired them at small sizes, I wasn't too impressed until after about a year. Then, as they (especially the males) got bigger than about 7", began to realize how beautiful they are. How come? Starting to look closer, since they would swim right up in front of my face, I recognized that the scaling - each individual scale I mean - "hides" or "reveals" a subtle, yellow-golden multi-coloration that varies slightly along the body that's always interesting and unique in good lighting, and that you'd never would know was there from pictures I'd seen. Don't get me wrong, I really admire their cousins, bocourti, the so-called "golden mojarra," but the pearsi I eventually began to realize are really GOLDEN as they mature. I used to look at them with reading glasses, too, for slight magnification since I've lost the 20-20 eyesight I had into my thirties, and man, they look freaky-beautiful-golden-GOLDEN up close. You'll really treasure those pearsei as they mature. So if they eat like pigs, not about to "hide" from the dinner table (or "hide" from anything when truly comfortable) consider the good omen.
Bocourti OTOH can be dangerous. They do "walk quietly" and can be quite "shy" but can certainly "carry a very big stick" when they get past about 9" (size depending on other variables). I'm not sure how aggressive they are towards other species. Raising them so very young together with others reduces the "risk" of violence. In the very long term, bocourti and pearsi together in the same tank? Maybe not. Honestly don't know. All I know is I'd keep watch that those beautiful bocourti don't start to hammer the (equally beautiful) pearsei - at around 2+ years of age?? Maybe they'll do fine as tankmates in a 260. Others would know better than I about that. Nothing to worry about for a pretty long time is my guess. I'm keeping a lone 7" H. bocourti male w/ several 3-5" (male & female) H. carpintis and female H. bocourti in a measly 55 gallon right now and no problems whatsoever thus far. They were all about half that size when I initially dropped them in.
Here's an 11" bocourti of mine w/ babies. In breeding, they can loose the fabulous "big orange sunburst" on the breast so don't be disappointed in this shot, because your animals will show lots of orange into adulthood:

BadOscar, you keep reminding me that you've chosen some OUTSTANDING animals!
