Common name: Electric Flame Scallop

General Information

The Electric Flame Scallop, scientifically known as Ctenoides ales, is a fascinating bivalve mollusk recognized for its vibrant red mantle and the unique, flashing light display it produces. This bioluminescent spectacle is not only mesmerizing but also serves as a defense mechanism to deter predators.

In the aquarium hobby, it is prized for its striking appearance and the dynamic light show, making it a popular choice for advanced marine aquarists looking to add a unique element to their tanks. However, due to its specialized care requirements and sensitivity to environmental changes, it is less commonly kept than other marine invertebrates.

Care

Caring for the Electric Flame Scallop can be challenging, as it requires pristine water conditions and a well-established tank. These scallops thrive in aquariums with live rock and plenty of hiding spots to mimic their natural reef habitat. They are filter feeders, relying on a steady supply of plankton and other small particulate foods suspended in the water column.

A mature reef tank with stable parameters is essential for their survival. They require a gentle water flow to help deliver food particles but not so strong that it dislodges them from their chosen location. Regular monitoring of water quality, including parameters like nitrate and phosphate levels, is crucial to prevent stress and ensure their health.

Diet and Feeding

In the wild, Electric Flame Scallops feed on plankton and other small organic particles. In captivity, replicating this diet can be challenging. They require frequent feedings of phytoplankton, marine snow, and other fine particulate foods. Feeding should be done several times a week to ensure they receive adequate nutrition.

Maintaining a healthy population of these filter feeders in a home aquarium often requires supplemental feeding, as natural food sources may not be sufficient. Care should be taken to avoid overfeeding, which can lead to deteriorating water quality.

Behavior and Compatibility

Electric Flame Scallops are relatively peaceful and can be kept with other non-aggressive tank mates. They are solitary creatures and do not require companions of their own kind. However, they can be sensitive to aggressive fish or invertebrates that may nip at their mantles or disturb their settled positions.

They are best suited for reef tanks with peaceful inhabitants. Care should be taken to avoid housing them with species that may be tempted by their waving tentacles, mistaking them for food.

Health and Common Issues

Electric Flame Scallops can be sensitive to changes in water quality and are prone to stress-related issues if conditions are not optimal. Ensuring stable water parameters and a consistent food supply is key to their longevity.

When selecting an Electric Flame Scallop, look for individuals with vibrant coloration and active movement of their mantle tentacles. Avoid scallops that appear retracted or have damaged mantles, as these can be signs of stress or poor health.

Routine maintenance, including regular water changes and monitoring for signs of stress or disease, will help maintain their health. Avoid sudden changes in lighting or water flow, as these can cause undue stress.

Habitat

Ctenoides ales is found in the Indo-Pacific region, inhabiting coral reefs and rocky outcrops. They are typically found at depths ranging from 3 to 50 meters, where they wedge themselves into crevices or under overhangs for protection.

They prefer environments with moderate to low water flow, allowing them to efficiently filter feed without being swept away. Mimicking these conditions in captivity is crucial for their well-being.
