đŊī¸ Diet & Feeding
Yellow Tangs are primarily herbivores and require a diet high in marine algae to maintain health and color.
Primary Diet (70%)
- Nori/Dried Seaweed - Offer daily on a clip
- Spirulina-based foods - Flakes or pellets
- Fresh macroalgae - Chaeto, Gracilaria, Ulva
- Algae sheets - Green, red, and brown varieties
Supplementary Foods (30%)
- Mysis shrimp - Enriched with vitamins
- Brine shrimp - Occasional treat
- Quality pellets - New Life Spectrum, TDO
- Frozen herbivore preparations
Feeding Schedule
- Feed 2-3 times daily
- Always have nori available
- Tangs graze constantly - small frequent feedings best
Nutritional Concerns
- HLLE Prevention: Vitamin-enriched foods, varied diet
- Soak food in vitamins: Selcon, VitaChem
- Avoid overfeeding proteins - Causes nutritional issues
đ Compatibility
Good Tankmates
- Clownfish
- Wrasses (most species)
- Anthias
- Gobies and blennies
- Dwarf angels
- Most peaceful community fish
Use Caution
- Other tangs - Can be aggressive; add simultaneously if keeping multiple
- Similar-shaped fish - May show aggression
- Other yellow fish - Sometimes territorial
Avoid
- Aggressive triggers
- Large predatory fish
- Multiple Yellow Tangs in small tanks
â ī¸ Health Considerations
- Ich susceptible: Quarantine all new specimens 4-6 weeks
- HLLE (Head and Lateral Line Erosion): Prevented with proper diet
- Stress-related illness: Provide adequate space
đĄ Tips for Success
- Quarantine is essential - tangs are ich magnets
- Provide constant algae source
- Add last to established tanks to reduce aggression
- UV sterilizer helps prevent disease
- Captive-bred specimens available and recommended
đ Summary
The Yellow Tang is a hardy, beautiful fish that makes an excellent addition to larger reef aquariums. Success depends on providing adequate space, a herbivore-focused diet with plenty of algae, and proper quarantine. With good care, Yellow Tangs can live over 20 years and maintain their brilliant coloration throughout their lives.
