Amblyeleotris Aurora: The Pinkbar Goby

A Vibrant Addition to Your Reef Tank

The Amblyeleotris aurora, commonly known as the pinkbar goby, is a captivating species of goby native to the reefs of the western Indian Ocean. Renowned for its striking appearance and fascinating symbiotic relationship with pistol shrimp, this fish has become a popular choice among marine aquarium enthusiasts.

Key Characteristics

• • Appearance: The pinkbar goby is characterized by its elongated body and five distinct, wide brown bands with diffused margins. Its caudal fin typically displays a vibrant yellow color with red spots or streaks.
  • Size: These fish can reach a maximum length of approximately 11 centimeters (4.3 inches).
  • Behavior: Pinkbar gobies are known to be relatively peaceful and often form pairs. They are highly territorial and may become aggressive towards other fish that enter their territory.
  • Habitat: In the wild, these gobies inhabit coral reefs at depths ranging from 5 to 40 meters. They are often found in association with pistol shrimp, with which they share a burrow.

Care in Captivity

• Tank Size: A minimum tank size of 30 gallons is recommended for a pair of pinkbar gobies.
• Water Parameters: Maintain stable water parameters, including temperature, salinity, and pH, to ensure the health of your fish.
• Diet: Pinkbar gobies are carnivorous and should be fed a diet of high-quality meaty foods, such as brine shrimp, mysis shrimp, and small pieces of fish.
• Tankmates: While these fish are generally peaceful, they may be aggressive towards other gobies or fish that resemble them. Choose tankmates carefully and provide ample hiding spots.

Symbiotic Relationship

One of the most fascinating aspects of the pinkbar goby is its symbiotic relationship with the pistol shrimp, Alpheus randalli. The goby provides visual alertness for the shrimp, while the shrimp creates and maintains a burrow for both organisms to share. This mutualistic relationship benefits both species by providing protection and a stable environment.

The Amblyeleotris aurora is a beautiful and intriguing fish that can add a touch of the ocean to any reef aquarium. With proper care and attention, these gobies can thrive in captivity and provide hours of enjoyment for their keepers.
