Dracula Goby

Geographical Origin and Habitat: Tropical Indian Ocean, almost exclusively native to the Maldives. Inhabits sandy areas adjacent to coral reefs at depths of 15 to 37 meters.

Taxonomy and Morphology: Belongs to the family Gobiidae. Reaches a maximum length of about 7 cm. Features an elongated, cylindrical body, large forward-facing eyes, and a tall, flag-like first dorsal fin.

Social Behavior: Peaceful but very shy goby. Lives in a mutualistic symbiosis with the pistol shrimp *Alpheus randalli*, sharing the burrow dug by the shrimp while acting as a vigilant lookout.

Coloration and Sexual Dimorphism: Stunning pattern of alternating oblique orange/red and white vertical bands on a light background. Head shows yellow coloration and metallic highlights. No visible sexual dimorphism.

Aquarium Setup: Requires a tank of at least 75 liters (20 gallons). A fine sand bed at least 5-7 cm deep, mixed with small shell fragments and rubble, is mandatory for burrow construction.

Diet and Feeding: Carnivorous micropredator. Must be fed 2-3 times daily with small frozen foods (mysis, brine shrimp, fish eggs, copepods). Only consumes food swept close to its burrow by currents.

Water Quality: Demands clean, stable water. pH 8.1-8.4, specific gravity 1.020-1.025, dKH 8-12, temperature 22-28°C (72-82°F). Sensitive to high nitrates.

Compatibility and Cohabitation: 100% reef-safe. Perfect for nano-reefs. Avoid aggressive tankmates, predatory fish, or fast-feeding species that consume food before the goby dares to emerge.

Aquarium Breeding: Captive breeding is extremely difficult. Eggs are laid inside the shared burrow, but the pelagic larval stage is nearly impossible to raise successfully.

Risks and Diseases: High jump risk: when startled, it darts upward. It is essential to cover the aquarium with a tight mesh screen or lid.
