The Golden Blue Eye Tang very rare and colorful surgeonfish. Golden Blue Eye Tangs are a uncommon variant of Ctenochaetus binotatus, also known as the Two-Spot Bristletooth Tang or Blue Eye Bristletooth Tang. The “golden” refers to a rare coloration or lighting effect some specimens display, usually more vivid in juveniles or under certain lighting.
Golden Blue Eye Tangs are semi-aggressive fish and shouldn't bother other fish, coral or inverts found in your tank. This makes them a great fish for reef tanks.
Tank Size: Golden Blue Eye Tangs reach a maximum adult size of around 7 inches and need to be kept in tanks that are at least 75+ gallons minimum, ideally 90+ for full-grown adults.
Aquascape: Lots of live rock for grazing and hiding.
Water Flow: Moderate to strong.
Lighting: No special needs; reef lighting is sufficient.
As a bristletooth tang, it specializes in grazing on film algae and detritus.
Main Diet: Constant grazer of live rock surfaces, Nori seaweed strips, Spirulina flakes, and Algae-based pellets.
Supplements: Mysis shrimp, Enriched brine shrimp (occasionally), Vitamin-soaked foods (to prevent HLLE).
Note: These tangs are great for keeping nuisance algae under control.
Generally peaceful, especially compared to Acanthurus tangs, but will get territorial toward other Ctenochaetus tangs. So it is best, to keep only one bristletooth per tank unless very large (180+ gallons).
Constant rock pickers, rarely seen idle. More introverted than Yellow or Kole Tangs, but will become bolder over time. The “blue eye” glow is especially intense under actinic lighting—super cool at dusk settings.
Disease Prevention: Susceptible to marine ich, quarantine recommended.
Stress: Provide ample hiding spots and reduce competition.
Feeding Variety: Prevent HLLE with a nutrient-rich, algae-heavy diet.
