Common name: Pineapple Sponges

Leucettidae, commonly known as Pineapple Sponges, are a family of calcareous sponges found in marine environments. These sponges are characterized by their unique vase-like or pineapple-like shapes, with a hard calcium carbonate skeleton. They are filter feeders, playing a crucial role in water purification within the aquarium. Pineapple Sponges are generally harmless to other reef inhabitants and can be a sign of a mature and healthy aquarium ecosystem. They often appear spontaneously in well-established tanks, growing on live rock or tank equipment.
