Astaxanthin Sources
Astaxanthin is the carotenoid that produces red, orange, and pink. Natural sources: krill, shrimp shells, salmon eggs, and synthesized astaxanthin in quality pellets.
XO Humpy Head, Hai Feng, and Okiko Plus all include astaxanthin in their color formulas.
Spirulina
Blue-green algae rich in protein and natural pigments. Enhances yellow, green, and overall vibrancy. Found in most quality fish foods.
Spirulina also supports immune function and gut health — bonus benefits beyond color.
- ✦Color shows after 4-6 weeks of consistent feeding.
- ✦Stress fades color — fix water issues first.
Live and Frozen Foods
Live blood worms, mysis shrimp, and krill provide bioavailable carotenoids that pellets cannot match.
Feed 2-3 times weekly alongside pellet base diet.
What Does NOT Work
Hormone injections — banned in most countries, damage long-term health.
Color drops added to water — useless and may harm gills.
UV LED lights marketed as "color enhancing" — light affects perceived color but does not create pigment.
Genetics Limits
A fish with weak color genetics will never become a top-color show fish, no matter what you feed. Color foods bring out the maximum the genes allow — not more.
Buy from reputable breeders if you want top color. Quality genetics + quality food = best result.
