What determines the color of a betta fish?
So, your betta fish’s color is determined by the color pigments in his color cells, which are found within the layers of your fishy friend’s skin. These color traits are known as phenotypes and are what is presented visually. The genes that comprise the traits are called genotypes.
Are betta fish genetically modified?
The millennium of careful selection gave rise to the stunning diversity of domestic betta fishes alive today, but also caused both wild and domestic betta fish to undergo vast genetic changes.
Are betta fish naturally colorful?
Betta fish come in a wide variety of solid colors from the most vivid to plain whites and black, yet many are also two-toned, and others have a range of different pigmentations. These fish are quite plainly colored in the wild, but those bred in captivity can be found in almost any vibrant color or shade.

Poor conditions in tanks or incorrect water temperature are the primary causes of stress in bettas, so always check the tank temperature, water parameters, and water quality before you do anything else. Bettas also change color as they age and in response to illness.
What is the Merle gene in bettas?
What Is the Marble Gene? Marbling is when a betta changes color: it can be red, blue, purple, or white, or a combination of both. Marble is also the name of a jumping gene, or transposon: a DNA sequence that can change its position in the fish genome.
How do I make my betta purple?

How do they make bettas glow?
While nearly identical in behavior to traditional domesticated bettas, GloFish Bettas produce a fluorescent protein that allows them to fluoresce under blue LED lights.
How are GloFish genetically modified?
GloFish (Figure 1) are a type of transgenic zebrafish (Danio rerio) that have been modified through the insertion of a green fluorescent protein (gfp) gene. Not all GloFish are green, however.
