prob cause grade A sp really are red even though majority of fish in our trade are lower grade sp and tend to be more orange but still hold the name. common names are made by us. scientific names are made by scientist. at least thats how it works in the world of plants
scientist would say archontophoenix cunninghamianna sp illiawarra, parachromis managuense...
for marketing purpose we would use king palm, jaguar... unless its really rare and it would only hold a scientific name.
Scientists don't name fish with common names....they use scientific binomial Latin names. Common names like "red bay snook" are created by the trade (FYI Red bay snook aren't all that colour, they are naturally greenish). For example, redtail shark sounds much cooler and more sellable than redtail carp.
I was thinking that maybe in their natural habitat; in the proper water and probably a certain amount of sunshine and there natural/normal foods,- without the chemically enduced water conditions and different lights and proccessed foods we provide them,- maybe they'd be 'red' if they were not stressed out so much? Even the 'wild' caught fish, I'm wondering what coloring those fish have before they are caught. Does any one go reef/coral diving?,** like on vacation-not capturing them-just looking at them in their natural living places, are they brighter colored there?
