Blue/Purple Sponge

Blue/Purple Sponge, Haliclona sp., makes a unique addition to the reef where proper provision is made for its particular needs. Originating throughout the Pacific, Red Sea, and Caribbean, this Sponge is found in varying shades of blues, lavenders, and purples. It requires low to moderate light levels. In aquariums with strong lighting, sponges should be avoided or placed in the shadows of rockwork to limit the overall amount of light exposure. Being a filter feeder, the Sponge demands very strong water flow. This is necessary to ensure that the sponge is receiving adequate quantities of water (and, more specifically, the nutrients in the water) to feed it. Sponges need excellent water conditions with low-to-non-existent nitrates and ammonia. Placement is not critical as long as it involves being placed on rock. Live Rock is best. Sponges do not do well in sandy substrates as it can tend to block the pores by which the sponge survives. It is absolutely imperative that no sponge should ever be exposed to oxygen, even in the acclimation transfer process. Oxygen will become entrapped in the fine pores of the sponge. The oxygen will prevent the water flow that carries nutrients throughout the sponge which will, in essence, suffocate the sponge. Supplementing the diet of sponges with preparations such as Marine Snow or Kent Phyto-Plan, or Kent Zoo-Plan will help ensure best health.
