Purple Tube Anemone- Cerianthus Pond Additives Blocks specific beams of lightCerianthus tube anemones are distinctive, non photosynthetic marine invertebrates (class Anthozoa) that construct and live within deep, fibrous, parchment like tubes buried in soft, sandy, or muddy substrates. Popular in marine aquariums for their vibrant, long, flowing tentacles (ranging from white to purple, orange, and green), they require intermediate care, moderate flow, and regular feeding of small meaty foods.
