Gobiosoma evelynae (Sharknose Goby)

Overview

  • Native to the Western Atlantic, commonly found in the Caribbean and Florida Keys.
  • Recognized for its slender body, vibrant blue and yellow coloration, and distinctive stripe along its head.
  • Acts as a cleaner fish, removing parasites from larger marine species.
  • Often found perched on rocks or corals while waiting for clients to clean.
  • Highly social and peaceful, making it an excellent addition to nano and reef aquariums.

Feeding

  • Omnivorous diet, consuming small invertebrates, plankton, and parasites.
  • Readily accepts frozen and live foods such as brine shrimp, mysis shrimp, and copepods.
  • Can be trained to eat high-quality flakes and pellets in a captive setting.
  • Frequent small feedings are recommended to mimic natural grazing behavior.
  • Beneficial in reef tanks where it naturally contributes to parasite control.

Habitat

  • Typically found near reefs, rock formations, and sandy bottoms.
  • Prefers small crevices and overhangs for shelter.
  • Best suited for aquariums with plenty of rockwork and coral structures.
  • Thrives in calm water conditions with stable parameters.
  • Ideal for nano tanks but can be housed in larger reef environments.

  • Compatible with small reef fish such as clownfish, gobies, and wrasses.
  • May be housed in pairs but requires adequate space to prevent territorial disputes.
  • Not suitable for aggressive species that may outcompete or harass them.
  • Reef-safe and poses no threat to corals or invertebrates.

Aquarium Behavior
