Neon rosy barbs. I love the pearlescent gold and pink color of these fish! Good community fish with other active species.
Unlike beef, which acquires its distinct red hue from contact with oxygen in the air, salmon meat gains its color through the fish’s diet. Out in the ocean, salmon eat lots of small free-floating crustaceans, such as tiny shrimp. These crustaceans are filled with molecules called carotenoids, which show up as pigments all over the tree of life. In fact, if you’ve ever known a kid who , you’ve seen carotenoids in action. It’s these carotenoids that account for the reddish color of the salmon, as well as the pink color of flamingoes and the red of a boiled lobster.
Carotenoids aren't just fed to exhibits and pets. If you walk down the grocery store aisles, you'll often see farmed salmon on display. Usually, somewhere on the package, you'll see a notice saying that "color" was "added" to the salmon to make it pink. But that color wasn't necessarily added after the fish was dead.

Based on price alone, the farm-raised fish is a steal — $3 per pound wholesale versus $10.50 per pound for wild caught. But a side-by-side comparison reveals a distinct difference in color: is light pink — almost orange — and has a flatter shine, without the rich hues of red.Salmon and trout owe their pink color to carotenoids deposited in their body fat. In fish farms and bird parks, carotenoids are added to the feed to create a pleasing pink color, but this has no effect on palatability or health. A synthetic "nature-identical" version of the carotenoid astaxanthin has been developed, and it is also possible (but expensive) to obtain commercial quantities of the natural color from cultured yeast and algae.
