Why Arowana Lose Color and the Risks of Forcing Quick Coloration
📝 Summary
Arowana can fade because of heat, poor water quality, or long-term pigment feeds, and some fading is permanent. Many keepers chase rapid, vivid color, but the tricks used—restricted feeding, lower temperature, lower pH, reduced water flow—stunt the fish's growth and rob it of its natural stature. Balanced development matters more than looks.
1 Why Arowana Lose Color and the Risks of Forcing Coloration
Common Causes of Fading
1. Heat. High temperatures can cause fading, but the fish’s color usually recovers on its own.
2. Poor water quality. Once the water is corrected, the body color can recover as well.
3. Long-term pigment feeds. Arowana fed coloring feeds for a long time may fade once those feeds stop, shifting from deep red to light red. This kind of fading is generally not reversible.
How to Keep an Arowana Red
1. Vary the diet, enrich the food, and feed at fixed times.
2. Keep the fish’s mood stable.
3. Provide moderate lighting—proper light is a major factor in coloration.
4. Control water flow, change water sensibly, and avoid both letting the tank go unchanged for too long and changing it too often; keep the water in good condition.
5. Keep the arowana alone. Mixed stocking or an overly complex mix of species easily stresses the fish and works against good coloration.
6. Install a good filtration system to keep water parameters stable.
7. Keep the water pH stable.
8. Avoid changing the tank’s layout so the environment stays consistent.
9. Keep the temperature around 28–30°C and hold it steady.
How to Make a Red Arowana Color Quickly
It is hard to develop both body shape and color at once. Keepers focused on color tend to restrict food intake and feed mainly shrimp-rich or carotene-rich foods to speed up coloration, but this hurts nutritional balance and normal growth. Other tricks include reducing water flow, lowering the temperature, lowering the pH, increasing lighting time, and lowering the water level while keeping the fish calm—all of which can prompt earlier coloring.
These measures do help color develop, but they also hinder proper development and leave the fish smaller than it should be.
Note: Never prize color over the fish’s normal growth and development. Ignoring healthy growth means that even a beautiful arowana will lack its natural, commanding presence. Balance coloration with growth.
