{"product_id":"sailfin-tang","title":"Pacific Sailfin Tang","description":"\u003ch2\u003ePacific Sailfin Tang\u003c\/h2\u003e\n\u003cp\u003eThe Pacific Sailfin Tang (\u003cem\u003eZebrasoma velifer\u003c\/em\u003e) — also called the Sailfin Tang, Eastern Sailfin Tang, Ringed Tang, or Sailfin Surgeonfish — is one of the most iconic, dramatically shaped, and universally recognizable large tangs available anywhere in the entire saltwater hobby. \u003cstrong\u003eA deep disc-shaped body displays five bold vertical bands of alternating yellow, cream, and rich dark tones running from front to back, dramatically punctuated by intricate spot and stripe detail within each band, a distinctive white head with yellow \"freckle\" markings on the nose, and a stunning yellow caudal fin with blue highlights — but the true showstopping feature is the species' signature exceptionally tall dorsal and anal fins that give the Sailfin Tang its name and can be raised or lowered at will, doubling the visual footprint of the fish when fully flared\u003c\/strong\u003e. When both fins are fully extended, a Pacific Sailfin Tang appears nearly circular and delivers one of the most dramatic display moments available anywhere in the marine hobby — genuine natural theater in your own reef tank.\u003c\/p\u003e\n\u003cp\u003eWhat makes the Pacific Sailfin Tang such an iconic centerpiece tang is the combination of extraordinary visual impact, active algae grazing behavior, hardy moderate care requirements, and the distinctive personality that has made this species one of the most memorable large tangs available to reef keepers. \u003cstrong\u003ePacific Sailfin Tangs are constantly active herbivore grazers that patrol live rock throughout the day consuming film algae, hair algae, and other nuisance growths — combined with their reef-safe temperament, hardy adaptability once established, and semi-aggressive but generally tolerant personality with non-tang tankmates, they are one of the best large centerpiece tangs available for reefers building substantial mixed reef or fish-only display systems\u003c\/strong\u003e. Widely considered a moderate-care species (much more accessible than expert-tier tangs like Achilles or Powder Blue), Pacific Sailfin Tangs make outstanding long-term specimens with 10 to 15+ year lifespans when housed in appropriately sized systems with quality algae-based nutrition.\u003c\/p\u003e\n\u003cp\u003eThe Pacific Sailfin Tang grows into one of the largest commonly-available tangs in the entire marine trade — this species requires substantial long-term tank size planning that many buyers underestimate when selecting appealing juvenile specimens. \u003cstrong\u003ePacific Sailfin Tangs sold at 1 to 4 inches as juveniles grow rapidly to an impressive adult size of 15 to 16 inches (38-40 cm), requiring a minimum 180-gallon aquarium for long-term care with 240+ gallons strongly preferred for adult specimens, and a horizontal tank length that provides adequate swimming distance for this constantly active large-bodied species\u003c\/strong\u003e. For serious reef keepers with large display systems (or firm plans to upgrade as the fish grows), quality herbivore feeding routines, and the commitment to long-term large tang husbandry, the Pacific Sailfin Tang delivers one of the most visually stunning and personality-driven large centerpiece tangs available anywhere in the entire saltwater trade.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3 style=\"color: #1a5a61;\"\u003eAvailable Options\u003c\/h3\u003e\n\u003cdiv style=\"display: table; width: 100%; border-collapse: separate; border-spacing: 8px 0;\"\u003e\n\u003cdiv style=\"display: table-row;\"\u003e\n\u003cdiv style=\"display: table-cell; width: 33.3%; background: linear-gradient(180deg,#f6fbf8 0%, #edf7f2 100%); border: 1px solid #d4e6e3; border-radius: 12px; padding: 13px 15px; vertical-align: top;\"\u003e\n\u003cp style=\"color: #1a5a61; margin: 0 0 6px;\"\u003e\u003cstrong\u003e1.5 to 2 Inches\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul style=\"margin: 0; padding-left: 1.1rem; font-size: 13px;\"\u003e\n\u003cli\u003eSmall juvenile specimen\u003c\/li\u003e\n\u003cli\u003ePeak proportional sail-fin height\u003c\/li\u003e\n\u003cli\u003eMost delicate handling required\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: table-cell; width: 33.3%; background: linear-gradient(180deg,#f6fbf8 0%, #edf7f2 100%); border: 1px solid #d4e6e3; border-radius: 12px; padding: 13px 15px; vertical-align: top;\"\u003e\n\u003cp style=\"color: #1a5a61; margin: 0 0 6px;\"\u003e\u003cstrong\u003e2 to 3 Inches\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul style=\"margin: 0; padding-left: 1.1rem; font-size: 13px;\"\u003e\n\u003cli\u003eEstablished juvenile specimen\u003c\/li\u003e\n\u003cli\u003eWell-developed color pattern and fin proportions\u003c\/li\u003e\n\u003cli\u003eBetter shipping tolerance than smallest size\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: table-cell; width: 33.3%; background: linear-gradient(180deg,#f6fbf8 0%, #edf7f2 100%); border: 1px solid #d4e6e3; border-radius: 12px; padding: 13px 15px; vertical-align: top;\"\u003e\n\u003cp style=\"color: #1a5a61; margin: 0 0 6px;\"\u003e\u003cstrong\u003e3 to 4 Inches\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul style=\"margin: 0; padding-left: 1.1rem; font-size: 13px;\"\u003e\n\u003cli\u003eLarger juvenile approaching sub-adult phase\u003c\/li\u003e\n\u003cli\u003eMost robust shipping and acclimation profile\u003c\/li\u003e\n\u003cli\u003eFull display presence from arrival\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cp style=\"font-size: 13px; color: #607078; margin-top: 10px; font-style: italic;\"\u003e\u003cstrong\u003eImportant:\u003c\/strong\u003e All size variants are juvenile specimens and will grow rapidly to 15-16 inches (38-40 cm) as adults.

Tank size planning MUST accommodate adult growth — minimum 125-gallon aquarium for juveniles with 180+ gallons standard for long-term care and 240+ gallons strongly preferred for adult specimens. Horizontal tank length matters more than total volume for active tangs — provide open swimming lanes across the length of the tank. This is a commonly outgrown species in the marine trade, and buyers must have appropriate long-term system planning or firm upgrade plans before purchase. \u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eSpecies identification note:\u003c\/strong\u003e Pacific Sailfin Tang (\u003cem\u003eZebrasoma velifer\u003c\/em\u003e) is often confused with Desjardin's Sailfin Tang (\u003cem\u003eZebrasoma desjardinii\u003c\/em\u003e) — the Red Sea and Indian Ocean counterpart species. Pacific Sailfin displays five vertical body bands fading to a yellow tail, while Desjardin's shows finer white spotting and stronger facial striations. These are distinct species with similar care requirements but genuinely different appearance and origin. \u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eTank environment:\u003c\/strong\u003e Provide an established mature reef or fish-only aquarium (6+ months set up) with extensive live rock for grazing surfaces, plenty of open swimming space across the length of the tank, and moderate to strong water movement with high dissolved oxygen levels (multiple powerheads and\/or protein skimming strongly recommended). Sailfin Tangs are constantly active swimmers that require substantial oxygen-rich water conditions to thrive long-term. A secure lid is advisable, especially during initial acclimation when the fish may be more skittish than usual. \u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eFeeding requirements:\u003c\/strong\u003e Feed multiple times per day with a rotating herbivore diet built around dried nori or seaweed sheets attached to the glass with a veggie clip (essential — this is the foundation of Sailfin Tang nutrition), supplemented with high-quality marine algae-based frozen foods, herbivore preparations, and vegetable-based pellets. While Sailfin Tangs will occasionally accept meaty foods offered to other tank inhabitants, they should NOT be fed a primarily carnivorous diet — extended lack of plant-based nutrition causes lateral line erosion and long-term health decline in tangs. \u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Pacific Sailfin Tangs are semi-aggressive with other Zebrasoma tangs and similar-shape\/similar-color fish, but are generally more tolerant of non-tang tankmates than many other tangs. One Sailfin per tank is the standard recommendation (multiple Sailfins are only compatible in very large tanks 300+ gallons with simultaneous introduction). Do not combine with other Zebrasoma species unless the tank is very large and both fish are introduced simultaneously. Pacific Sailfin Tangs are completely reef-safe and will not harm corals or invertebrates — they serve as excellent natural algae control in reef displays. Like all tangs, Pacific Sailfins have sharp retractable caudal spines (the \"scalpel\") on either side of the tail base — handle with care during netting or acclimation as these spines can cause deep lacerations to human handlers and other fish. Sailfin Tangs are moderately ich-prone (like all tangs) — quarantine and observation for 2 to 4 weeks before display tank introduction is recommended, and buyers should have ich treatment protocols available if needed.\u003c\/div\u003e\n\u003chr\u003e\n\u003ch3 style=\"color: #123844;\"\u003e🔍 Aquarium Insights\u003c\/h3\u003e\n\u003cp\u003eThe Pacific Sailfin Tang is one of the most iconic and visually dramatic large tangs available to reef keepers:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eExceptionally tall sail-like dorsal and anal fins that double the fish's visual footprint when fully flared — genuine natural display theater in your own reef tank\u003c\/li\u003e\n\u003cli\u003eFive bold vertical bands of yellow, cream, and dark tones with intricate spot and stripe detail — one of the most distinctive banded tang patterns in the entire marine trade\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eA moderate-care iconic large centerpiece tang for substantial reef or fish-only displays — the classic Zebrasoma species that anchors serious large mixed reef systems with dramatic display presence, active algae grazing, and 10-15+ year longevity for reefers with appropriate long-term tank size planning\u003c\/strong\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003ch3 style=\"color: #123844;\"\u003eLearn More\u003c\/h3\u003e\n\u003cp style=\"margin-bottom: 0;\"\u003eFor detailed species information, compatibility, and care tips, visit our \u003cstrong\u003e\u003ca href=\"https:\/\/www.macroalgaefarms.com\/pages\/species-library\" style=\"color: #1d5c78;\"\u003eSpecies Library\u003c\/a\u003e\u003c\/strong\u003e.\u003c\/p\u003e\n\u003chr style=\"margin: 24px 0;\"\u003e\n\u003cdiv style=\"background: #f6f8f9; border: 1px solid #dde4e7; border-left: 4px solid #8a98a0; border-radius: 10px; padding: 13px 15px; font-size: 13px; color: #607078; line-height: 1.65;\"\u003e\n\u003cstrong style=\"color: #46545b;\"\u003eLivestock Disclaimer\u003c\/strong\u003e\n\u003cp style=\"margin: 8px 0 10px;\"\u003eDue to natural variation, the Pacific Sailfin Tang you receive will be hand-selected from current inventory within the selected size variant (1.5-2\", 2-3\", or 3-4\") displaying the characteristic vertical band pattern and yellow-cream-dark coloration.
