White Cap Goby Lotilia graciliosa

White Cap Goby Lotilia graciliosa

  The White Cap Goby (Lotilia graciliosa) is a small reef-safe fish valued for its bright white head, peaceful nature, and unique behavior. Found in tropical reef habitats of the Western Pacific, this species is often seen living near burrows and sandy areas where it feels secure. Like many other Gobies, the White Cap Goby spends much of its time hovering close to the substrate while watching for food and potential threats. Its modest size, calm temperament, and interesting relationship with burrow-dwelling shrimp make it a popular choice for established reef aquariums. When provided with ample rockwork, sand, and hiding places, the White Cap can be a fascinating addition to a peaceful marine aquarium.
