What's their growth rate like? When do they start to color up? Do they all get the golden yellow color like the first picture or a brown gold color like the second? Feel free to share your pics of your pearsei.

Their growth rate is typical for a cichlid, grow pretty fast to about 4 inches and then slows down there after. As for coloring both pics are of Pearsei showing typical coloration, the only difference is the background which does affect how their coloration is perceived. Personally I always thought of Pearsei as green and brown coloration and the Golden Mojarra/ Herichythys Bocourti as the golden colored member of the Herichythys group. Here's a pic of my old 10 incher.
I purchased mine at about 6inches and he grew another 5inches in 8 months. He displayed more yellow when I had him in a tank with lighter décor/gravel. In these pics he's in a tank with black gravel and black background displaying more brown. they produce a lot of waste and are susceptible to HITH so good filtration and tank maintenance is a must.
Pearsei are almost totally vegetarian in nature, eating algae, aquatic plants and terrestrial leaves and fruits from overhanging trees. They will show best color if the food they receive is high in algae and plant based vitamins. Color enhancing pellets designed for koi often contain those elements, and don't contain the animal proteins that can damage the pearsei's long digestive tract.
My pearsei grew very quickly to over 15" on low protein koi pellets, romaine lettuce and peas. Sorry, I didn't have a camera at the time I had the pearsei.
I now have bocourti, and am feeding the same diet I used above for pearsei.
I found that they grow very fast compared to most other CA cichlids that I've had. I think it's a function of their incredible appetites. In one year they grew from and inch or so to 6-8"". Heavily vegetarian, love romain lettuce, peas especially. Are real pigs for most any foods. I fed them various pellet foods which they thrived on. They are always first to the food and really hog it. I find them very similar to 'bocourti', a little less aggressive though. They've topped out at around 14" TL, and are getting 'taller' (bulkier) with age.
I had 6 of them, 4 of which lived for 8 years in a 240 gallon. I had one male and three females. Not the easiest species to breed, although I have seen others that have had success. Very thick, male was 16.5" when he died. Females were 14-15"". Males will have a high head profile, and the vent is pretty obvious once they reach 12" or so. I really enjoyed them, and would get them again if I thought I could breed them. Like others have said, high bio-load. Mine grew very quickly from 1" to about 10-12", then the growth slowed on the length.
