Plagiotremus rhinorhynchus - Bluestriped Fangblenny

Plagiotremus rhinorhynchus (Bluestriped Fangblenny)

Overview

  • Native to the Indo-Pacific region, commonly found near coral reefs and lagoon habitats.
  • Distinctive slender body with alternating bright blue and black horizontal stripes.
  • Known for its unique behavior of mimicking cleaner wrasses to approach other fish and occasionally nip at scales or fins.
  • Recommended for intermediate to advanced aquarists due to its specialized behaviors and dietary needs.

Feeding

  • Carnivorous; naturally feeds on mucus, scales, and skin of other fish in the wild.
  • Accepts frozen foods such as mysis shrimp, brine shrimp, small marine preparations, and finely chopped seafood.
  • Multiple small feedings daily are ideal to maintain optimal health and coloration.
  • Variety and consistency in diet essential for nutritional balance and health.

Habitat

  • Prefers moderately sized aquariums (minimum 30 gallons) with ample hiding spaces and live rock structures.
  • Stable, mature aquarium environment crucial for success.
  • Provide numerous hiding spots, caves, and crevices to mimic their natural habitat.
  • Moderate water circulation and effective filtration necessary for maintaining excellent water conditions.

Fish Care

  • Optimal water temperature: 72-78°F (22-26°C).
  • Recommended pH: 8.1-8.4; specific gravity: 1.020-1.025.
  • Sensitive to water parameter fluctuations; regular monitoring and consistent aquarium maintenance important.
  • Regular checks for signs of marine diseases and parasites; prompt action ensures optimal health.

Compatibility

  • Semi-aggressive; suitable for aquariums with larger, robust fish species.
  • Reef-safe with caution; may occasionally nip at other fish.
  • Recommended tank mates include larger clownfish, tangs, dwarf angelfish, and other semi-aggressive marine species.
  • Should be monitored closely for compatibility, particularly with peaceful or slow-moving tank mates.

Aquarium Behavior

  • Highly active and curious swimmer, often exploring rockwork and open areas.
  • May display aggressive mimicry behavior by approaching other fish to nip scales or mucus.
  • Providing ample hiding spots and clear territories helps minimize aggressive interactions.
  • Interactive with aquarium caretakers, often engaging actively during feeding sessions.
