Razor Goby Oxymetapon Cyanoctenosum

Overview:
The Razor Goby is a small, slender, and striking goby species known for its elongated, razor-thin body and vivid blue and black markings. Highly cryptic and fast-moving, it often hides among coral branches or rock crevices, making it a fascinating addition to reef aquariums for those seeking active, visually striking fish.

Origin:
Native to the Indo-Pacific, particularly found on shallow reef slopes and lagoons, where it occupies small crevices and coral shelters.

Feeding:
Carnivorous – feeds on zooplankton, small crustaceans, and micro-invertebrates. In captivity, it can be offered frozen mysis shrimp, brine shrimp, finely chopped seafood, and specialized micro-pellets. Frequent small feedings are recommended to mimic natural feeding behavior.

Tank Mates:
Peaceful and reef-safe, compatible with small, non-aggressive fish. Avoid larger predatory species that may prey on it or outcompete it for food.

Aggression:
Low. Territorial only in its immediate hiding spot but otherwise very peaceful.

Experience Level:
Intermediate. Requires a well-established reef tank with plenty of hiding spaces and stable water parameters. Best kept in a tank with moderate to heavy live rock cover.

Water Parameters:

• Temperature: 74–78°F (23–26°C)
• pH: 8.1–8.4
• Salinity: 1.020–1.025
• Minimum Tank Size: 20 gallons

The Razor Goby (Oxymetapon cyanoctenosum) is a beautiful, small, and active reef dweller that adds movement, color, and natural behavior to coral aquariums. Its striking coloration and slender profile make it an attractive choice for intermediate hobbyists seeking unique goby species.
