Atlantic Red Tree Sponge - Large

Atlantic Red Tree Sponge — Agelas conifera

The Agelas conifera Atlantic Red Tree Sponge is a striking marine invertebrate with a branching, tree-like structure and vibrant red coloration that adds bold visual interest to any reef tank. Slow-growing and peaceful, it filters water for plankton and microfauna, contributing to water quality while providing natural habitat for small reef organisms. Its unique texture and color make it a standout feature in mature reef aquariums.

Atlantic Red Tree Sponges thrive in established reef tanks with stable water parameters, moderate flow, and plenty of space to grow without obstruction. Introduce only to mature systems to ensure stable water conditions. A minimum tank size of 30 gallons is recommended to provide space for natural expansion and healthy growth.

Their diet consists primarily of planktonic foods and finely powdered or frozen foods from San Francisco Bay Brand, Hikari, PE, TDO, and New Life Spectrum to support filter-feeding and vibrant coloration. Target feeding encourages active water filtration and overall health.

Approximate product size: 3"–6" branches (varies by availability)
