Sponges (phylum Porifera)

spongeSponges belong to the phylum Porifera and represent the first evolutionary steps in the single-celled organisms organizing themselves into multicellular animals.

They have been highly successful and have over 8,000 species currently listed with the majority being marine sponges. Primarily adapted to filter organic particles and plankton from the water column, some species have incorporated photosynthetic algae into their tissue.

Since they rely on an unobstructed surface area, problems can arise inside your saltwater aquarium where high nutrient levels can fuel the growth of aquarium algae which will obstruct the sponges. Also large amounts of detritus may also comprise the sponges ability to feed.


On a brighter note with the right food at regular basis, a sponge can be kept successfully inside an aquarium.
