Overview

  • Native to the Indo-Pacific, commonly found in shallow reef flats and sandy coastal lagoons.
  • Easily identified by its elongated body, featuring pinkish hues and scattered speckled markings.
  • Frequently observed in a symbiotic relationship with pistol shrimp, sharing burrows for protection.
  • A hardy and peaceful species that thrives in well-maintained aquariums with stable water conditions.
  • Best kept in an aquarium with live sand, small rock formations, and a gentle water flow.

Feeding

  • Carnivorous, feeding primarily on small crustaceans, copepods, and plankton in the wild.
  • Requires a varied diet of frozen mysis shrimp, brine shrimp, and finely chopped seafood.
  • Readily accepts high-quality marine pellets and flakes designed for carnivorous fish.
  • Should be fed multiple small meals per day to support energy levels and maintain overall health.
  • A balanced diet enhances its coloration and ensures a strong immune system.

Habitat

  • Prefers sandy-bottomed reef environments with ample burrowing space.
  • Frequently seen resting near burrow entrances, monitoring surroundings for threats.
  • Aquarium setups should include a fine sand substrate and rock formations to encourage natural behaviors.
  • Requires stable water conditions and moderate water flow to maintain a stress-free environment.
  • Providing a secure habitat with shaded areas and caves supports its well-being.

Fish Care

  • Optimal water temperature: 74-80°F (23-27°C) to support healthy metabolic function.
  • Preferred pH range: 8.1-8.4, with a salinity level of 1.020-1.025.
  • Requires stable water quality and regular maintenance to prevent health issues.
  • Reef-safe and does not pose a threat to corals or invertebrates.
  • Providing a sandy substrate and burrow-friendly areas encourages its natural behaviors.

Compatibility

  • Peaceful and best suited for community tanks with other non-aggressive fish.
  • Compatible with clownfish, wrasses, cardinalfish, and various reef-safe species.
  • Often pairs with pistol shrimp, forming a mutually beneficial relationship.
  • Should not be housed with aggressive fish that may intimidate or disrupt its burrowing activity.
  • Providing an environment with adequate hiding spaces reduces territorial conflicts.

Aquarium Behavior

  • A shy but observant species that spends much of its time near its burrow.
  • Frequently seen interacting with its symbiotic shrimp partner, engaging in burrow maintenance.
  • More confident when housed in a stable, stress-free environment with plenty of cover.
  • Providing structured aquascaping encourages natural foraging and burrowing behaviors.
  • Over time, it may recognize its caretaker and display increased activity during feeding times.
