Blue Hippo Tang Medium (TR) | Reef Safe, Herbivore

The Blue Hippo Tang (Paracanthurus hepatus) is one of the most iconic reef fish in the hobby — brilliant electric-blue body, jet-black palette pattern, and a flash of yellow on the tail. This tank-raised medium specimen is hardier than wild-caught counterparts, ships with a stronger immune system, and is already accustomed to prepared foods. An intermediate-care herbivore best suited for established reef tanks 125 gallons or larger.

Blue Hippo Tangs are reef safe and generally peaceful with most other species. Avoid keeping with conspecifics or other surgeonfish in tanks under 200 gallons — they will fight. They are very prone to marine ich (Cryptocaryon), so a quarantine period and a stable, established display tank are essential.

Good tank mates: Clownfish, chromis, cardinalfish, firefish, royal grammas, wrasses, gobies, blennies, peaceful angels, reef-safe shrimp, snails, and hermit crabs.

Avoid: Other tangs (unless added simultaneously to a 200+ gallon system), large aggressive predators (groupers, large triggers, lionfish), and any nippy fish that may stress the tang.

• BRS Nori Seaweed Sheets (20 g) — daily greens, essential for tang gut health
• Two Little Fishies Sea Veggies Clip — for serving nori in the tank
• SFBB Freeze-Dried Mysis Shrimp — protein supplement
• Reef-grade salt mixes — for stable parameters during water changes
• Saltwater test kits — keep nitrate, phosphate, alkalinity, and salinity in check
• Marine medications — keep ich and parasite treatments on hand for QT

Why pickup only?
Tangs are highly stress-sensitive and notoriously prone to ich during shipping transitions. Selling pickup-only lets us hand off a healthy fish from our QT system directly to your bucket — no overnight box, no temperature swings, no DOA risk.

Is this fish reef safe?
Yes — Blue Hippo Tangs do not bother corals or invertebrates. They actively help graze nuisance algae like film algae and short hair algae.

Tank-raised vs wild-caught — what's the difference?
Tank-raised (TR) Blue Tangs were bred in captivity, never exposed to wild parasites, eat prepared foods from day one, and adapt much faster to home aquariums. They are more expensive but dramatically more likely to thrive long-term.

Can I add this to a 90-gallon tank?
We don't recommend it. Blue Hippo Tangs grow to roughly 12 inches and need long horizontal swim space. 125 gallons is the minimum and 180+ is ideal for an adult.
