The Yellow Coris Wrasse — Beauty, Balance, and Energy in Your Reef
Few fish bring as much life and function to a reef aquarium as the Yellow Coris Wrasse (Halichoeres chrysus).
This bright, active species isn’t just stunning — it’s a natural helper that keeps your tank clean and vibrant.
A Natural Reef Guardian
The Yellow Coris is famous for its role as a micro-pest hunter — feeding on small flatworms, nudibranchs, and pyramid snails.
It spends its days patrolling the rock work and sand, always on the move, adding motion and character to your tank.
💡 Pro tip: Always provide a fine sand bed (2–3 inches minimum) so it can bury itself at night or when stressed.
It’s one of the most peaceful wrasses, ideal for community tanks and reef setups.
Nutrition: The Key to Vibrant Color and Health
In the wild, wrasses feed on a mix of small crustaceans, worms, and larvae — a rich, balanced diet high in marine proteins and natural carotenoids.
In the aquarium, variety is crucial. Combine high-quality frozen food, pellets, and enriched supplements to support long-term health and coloration.
Recommended nutrition routine:
-
Daily feeding: Elos SVM (Soft Vitamin Marine) — a complete soft food rich in natural proteins, omega-3s, and pigments.
-
Supplement support: Add vitamin and amino-acid boosters such as Elos Omega or Elos Pro Skimmer Food Soak to enhance nutrient absorption.
-
Weekly vitality: Use Elos SV.M along with Reef Vitamins to reinforce immune response and color vibrancy, especially during acclimation or stress.

Why Supplementation Matters
Even with good feeding, closed systems often lack trace nutrients and vitamins that wild fish get from their environment.
Supplementing your fish diet helps prevent color fading, loss of appetite, and low energy levels — especially for active hunters like the Yellow Coris Wrasse.
Top 3 signs your fish may need supplements:
-
Dull coloration or faded yellow tones
-
Reduced activity or hiding too often
-
Frayed fins or slow wound recovery
Adding Elos SVM and vitamin blends can make a visible difference within weeks.
Final Thoughts
The Yellow Coris Wrasse is more than just a pretty yellow flash — it’s a dynamic and essential part of a balanced reef ecosystem.
Feed it well, supplement smartly, and it will reward you with color, activity, and a healthier tank.
