Marine fish color doesn't stay vibrant on a bare-bones diet — it depends on ongoing access to color-supporting nutrients, which is the specific job Dymax Colour Plus Food is built to do. It comes in small and medium pellet sizes so you can match it to the fish you're feeding.
Why Color Fades Without the Right Diet
Many of the reds, oranges, and yellows in marine fish come from carotenoid pigments that fish can't synthesize on their own — they have to come from diet. A food lacking these compounds can leave otherwise healthy fish looking duller than they should, even with good water quality and no obvious health issues.
What Colour Plus Food Offers
- Natural color-enhancing ingredients that supply the pigments marine fish need to maintain vibrant coloration.
- Small and medium pellet sizes to match different fish mouth sizes across a mixed marine community.
- Balanced nutrition beyond just color — supporting general condition alongside pigmentation.
Feeding Tips
- Feed consistently — color improvements build gradually over weeks of regular feeding, not overnight.
- Match pellet size to fish, using the small pellet for smaller mouths and the medium pellet for larger fish.
- Rotate with other quality foods for dietary variety alongside the color-boosting benefit.
