Add a bolt of contrast and motion to your reef with the stunning Powder Brown Tang! Featuring a jet-black face, bright white cheek patch, glowing golden body, and bold orange highlights on the dorsal and anal fins—this tang delivers nonstop action and color from the second it enters your system.

But what really sets ours apart? At YoCamron’s Aquatics, we don’t just sell tangs—we restore them. Powder Browns are notorious for poor survival rates when rushed through import—they’re highly susceptible to marine ich, bacterial infections, and stress-related decline. That’s why our Powder Browns undergo our signature 10-week quarantine process designed to transform them from delicate to durable.

Our Quarantine Protocol Includes:

• Copper + Chloroquine Phosphate to treat and prevent ich and velvet
• Kanamycin + Nitrofurazone to eliminate internal and external bacterial infections
• Formalin baths to eradicate flukes and other ectoparasites
• Fenbendazole + Levamisole for full-spectrum internal deworming
• Nutritional rehab with Nori, Spirulina flakes, PE Mysis, and garlic-soaked pellets to boost appetite and immunity

What You’re Getting:

• A fully eating, socialized tang with a strong appetite and a clean bill of health
• Zero parasites, zero guesswork, zero drama—we do the hard work so you don’t have to
• A vibrant swimmer that thrives in reef tanks or FOWLR systems, and actively grazes nuisance algae
• A fish that ships safely, transitions quickly, and stands up to life in your display tank

Compatibility Tips:

Best kept as the only Acanthurus tang in smaller systems unless introduced carefully to large tanks (180+ gallons). Gets along well with wrasses, angels, clowns, and most reef-safe fish. Provide high oxygenation, strong flow, and plenty of swimming space for long-term success.

If you’ve ever struggled with this species in the past, this is your second chance—with a Powder Brown Tang from YoCamron’s Aquatics, you’re not buying a fish… you’re investing in a survivor.
