Electric Flame Scallop (Ctenoides ales) – Disco Clam / Electric Clam Add a mesmerizing spectacle to your reef aquarium with the stunning Electric Flame Scallop (Ctenoides ales), also known as the Disco Clam or Electric Clam! This exotic Indo-Pacific bivalve features a vibrant red-orange mantle fringed with long, flowing tentacles and jaw-dropping “electric” blue-white flashes that ripple across its edges like lightning or a miniature disco ball. These hypnotic pulses aren’t true bioluminescence but rapid reflections of aquarium lighting created by specialized reflective silica nanostructures—creating an illusion of pulsing sparks that captivates viewers day or night. Growing to about 1–3 inches, this peaceful filter feeder thrives in mature reef systems with pristine parameters, moderate flow, and shaded crevices or ledges where it builds a small nest of rocks and coral bits for security. It requires dedicated supplementation with fine phytoplankton and zooplankton (5–40 microns) via broadcast or target feeding to survive long-term, as it’s a strict plankton consumer and expert-level care is essential for success. Reef-safe and compatible with non-predatory tankmates, the Electric Flame Scallop is a rare, high-impact showpiece for advanced aquarists seeking something truly extraordinary.
