Well if you think of it FH's are hybrids. I mean most species of cichlid are found in multiple places in the world naturally. I read an old article in one of those old dusty 1970's fish books that mentioned specifically uropthalmus and synspillums that actually were found to travel through the ocean to other freshwater habitats. They found them in south east asia as well as where they are commonly found in south america. Wish I could find the book to scan and post on here.
Also, I mean as a FH breeder you do notice better color, size, and shape of fry in saltier alkaline water. Saltier in my case meaning aquarium salt (in my case mortons water softener that you find at home depot) treatments that are twice a normal dosage. I mean I never tested my SG but next time I just might. My pH is 8.2-8.5 so thats a salt range.
Makes you think doesn't it?
Also, there have been notes that breeders in Malaysia are keeping there B grade adults in salt to show them better. Rumor or not it supports what you saw.
