Common name: Helena Anthias
General Information
The Plectranthias helenae, commonly known as the Helena Anthias, is a stunning and rare addition to the marine aquarium trade. Native to deep reef environments in the Indo-Pacific, this species is highly sought after for its unique appearance and peaceful demeanor.
Due to its deep-water habitat, the Helena Anthias is less commonly encountered in the aquarium trade compared to other anthias species. Its rarity and the challenges associated with its collection make it a prized specimen for advanced hobbyists and collectors. However, its small size and relatively peaceful nature make it an excellent candidate for nano and mid-sized reef aquariums.

Care
The Helena Anthias requires a well-established aquarium with plenty of live rock for hiding and exploration. As a deep-water species, it thrives in dimly lit environments, so subdued lighting or shaded areas in the tank are ideal. This fish is best suited for aquariums with stable water parameters and moderate water flow to mimic its natural habitat.
Providing ample hiding spots, such as caves and crevices, is essential for this shy species. It is a relatively hardy fish once acclimated but may require careful monitoring during the initial introduction to ensure it adjusts well to its new environment.
Diet and Feeding
In the wild, Plectranthias helenae primarily feeds on zooplankton and other small invertebrates. In captivity, it should be offered a varied diet that includes high-quality frozen foods such as mysis shrimp, brine shrimp, and finely chopped seafood. Enriched foods and small-sized pellets designed for carnivorous marine fish can also be provided.
Feed this species small portions multiple times a day to replicate its natural feeding habits and ensure it receives adequate nutrition. A varied diet will help maintain its vibrant coloration and overall health.
Behavior and Compatibility
The Helena Anthias is a peaceful and shy species, making it an excellent choice for community reef tanks. It is best kept with other non-aggressive tank mates, such as small gobies, blennies, and wrasses. Avoid housing it with overly aggressive or territorial species that may outcompete it for food or stress it out.
This species is typically solitary or found in small groups in the wild. In captivity, it can be kept solo or in a pair. If keeping multiple individuals, ensure the tank is large enough to provide ample hiding spaces and reduce territorial disputes.
Rarity and Availability
The Helena Anthias is considered rare in the aquarium trade due to its deep-water habitat and the challenges associated with its collection. Its price reflects its rarity, making it a premium choice for advanced hobbyists. Captive-bred specimens are not yet available, further contributing to its exclusivity.
