Hypoplectrus guttavarius - Saddled Basslet

Hypoplectrus guttavarius (Saddled Basslet)

Overview

  • Found in the warm waters of the Caribbean, particularly around coral reefs and rocky coastal areas.
  • Easily identifiable by the distinctive dark saddle-like markings along its dorsal region.
  • A relatively small yet assertive species, often seen patrolling its territory.
  • Best suited for reef tanks with plenty of crevices and hiding spaces.

Feeding

  • Primarily carnivorous, feeding on small crustaceans, zooplankton, and tiny reef-dwelling invertebrates.
  • Accepts frozen mysis shrimp, enriched brine shrimp, and high-protein pellets in captivity.
  • Providing a varied diet supports both health and vibrant coloration.
  • Feeding twice daily ensures steady energy levels and natural hunting behavior.

Habitat

  • Prefers reef structures with abundant hiding places such as caves and ledges.
  • Adapts well to aquariums that mimic natural reef formations with live rock.
  • Requires moderate water movement to simulate its native habitat.
  • Thrives in a well-maintained tank with stable conditions.

Fish Care

  • Optimal water temperature: 74-80°F (23-27°C).
  • pH level: 8.1-8.4, with a specific gravity of 1.023-1.026.
  • Resilient but benefits from consistent water quality and regular maintenance.
  • Acclimates best in established aquariums with minimal fluctuations in parameters.

Compatibility

  • Semi-aggressive; can be territorial towards similar-sized fish.
  • Best housed with equally assertive tank mates such as wrasses, dwarf angelfish, and larger clownfish.
  • Should not be housed with overly timid species that may be outcompeted for food.
  • Does well in a reef tank but may nip at very small shrimp or slow-moving invertebrates.

Aquarium Behavior

  • Frequently seen darting among rock crevices and patrolling its designated territory.
  • May exhibit dominance displays, especially if kept with other basslets.
  • Becomes more active and confident as it acclimates to its surroundings.
  • Enjoys perching on rock formations while observing its environment.
