Care
Vulcan Triplefins are relatively hardy and can adapt to life in a well-established aquarium. They require a tank with plenty of live rock and crevices for hiding and foraging. These fish are micro-predators, feeding on small invertebrates, so a varied diet of small live or frozen foods like copepods, brine shrimp, and mysis shrimp is essential for their health.
Reproduction
Like many triplefin species, Helcogramma vulcana exhibits a polygynous mating system where males may mate with multiple females. They are known to guard their eggs until hatching. In an aquarium setting, breeding Vulcan Triplefins can be challenging due to their specific reproductive behaviors and requirements for egg care.
Habitat
Helcogramma vulcana is found in the Western Pacific, specifically around Indonesia. They inhabit shallow, coastal reef environments where they can be seen darting among coral rubble and rocky substrates. In the wild, they are typically found at depths ranging from the intertidal zone to about 20 meters.
