Common name: Rosy Sponge

General information

The Rosy Sponge, scientifically known as Myxilla rosacea, is a colorful and attractive marine sponge species that can add a touch of natural beauty to any reef aquarium. This sponge is characterized by its vibrant pink to rosy coloration and its encrusting growth form, which allows it to spread over rocks and other surfaces in the tank.

Sponges like Myxilla rosacea are filter feeders, drawing water through their porous bodies to extract nutrients. They play a crucial role in the marine ecosystem by filtering out particulate matter and bacteria, thus contributing to water clarity and quality.

Care

Caring for Myxilla rosacea requires stable water conditions and moderate to strong water flow to mimic their natural habitat. They thrive in well-established aquariums where they can receive a constant supply of planktonic food. It's important to maintain high water quality, as sponges are sensitive to elevated levels of nitrates and phosphates.

Reproduction

Reproduction in sponges like Myxilla rosacea can occur both sexually and asexually. Sexual reproduction involves the release of sperm into the water column, which then fertilizes eggs in other sponges. Asexually, sponges can reproduce by budding or fragmentation, where a piece of the sponge breaks off and grows into a new individual.

Habitat

Myxilla rosacea is found in a variety of marine environments, from shallow waters to deeper regions. They often inhabit rocky substrates and reef structures where they can securely attach and spread. In the aquarium, they should be placed in areas with good water flow but not in direct, strong current, which could damage their delicate structure.
