Valenciennea Puellaris (The Diamond Goby)

Overview

• Native to the Indo-Pacific, commonly found in sandy coastal regions and shallow reef environments.
• Recognized for its elongated body, silver-white coloration, and bright orange markings along the head and fins.
• A peaceful species known for its burrowing behavior and sand-sifting activity, helping to maintain a clean substrate.
• Often found in pairs, forming a strong bond and working together to construct burrows.
• Best suited for aquariums with a fine sandy substrate, live rock formations, and stable water conditions.

Feeding

• Carnivorous, primarily feeding on small invertebrates, worms, and crustaceans found in the sand.
• Thrives on a diet of frozen mysis shrimp, brine shrimp, copepods, and high-quality marine pellets.
• Readily sifts through the sand to extract food, a natural behavior that benefits aquarium substrate health.
• Should be fed multiple times per day to ensure proper nutrition and sustained energy levels.
• A varied diet rich in protein supports growth, coloration, and overall well-being.

Habitat

• Prefers sandy-bottom reef environments with ample rock structures for burrowing and shelter.
• Frequently seen hovering above the sand, actively sifting through the substrate in search of food.
• Aquarium setups should include a deep sand bed to accommodate burrowing behavior.
• Requires stable water parameters and strong filtration to maintain water clarity and quality.
• Providing plenty of open substrate ensures a natural and comfortable environment.

Fish Care

• Optimal water temperature: 74-80°F (23-27°C) to maintain metabolic stability.
• Preferred pH range: 8.1-8.4, with a salinity level of 1.020-1.025.
• Requires regular water changes and a well-maintained sand bed to prevent debris buildup.
• Reef-safe and does not pose a threat to corals or other tank inhabitants.
• Providing a suitable diet and ample space encourages natural behaviors and reduces stress.

Compatibility

• Peaceful and best housed with other non-aggressive species.
• Compatible with clownfish, tangs, wrasses, and other reef-safe tankmates.
• Should not be housed with large predatory fish that may view it as prey.
• Best kept in pairs to encourage social interactions and natural burrowing behavior.
• Providing multiple hiding spots and soft sand enhances overall comfort and security.

Aquarium Behavior

• A calm and diligent species that spends most of its time sifting through sand.
• Frequently observed burrowing or resting near its constructed tunnels.
• More confident in a well-established aquarium with plenty of substrate to explore.
• Providing a fine sandy bottom and rock formations allows for natural behavior and security.
• Over time, it may become accustomed to its caretaker and actively participate during feeding times.
