Freshwater Sponge (Spongilla lacustris — Starter Culture)

Spongilla lacustris is a native European freshwater sponge found in clean, still or slow-moving waters, providing a living substrate for invertebrate microfauna and a fascinating biological filtration component in species or biotope aquariums. This listing provides a starter culture fragment attached to a small piece of rock, ready to be placed in a mature, established aquarium. Freshwater sponges require very clean water with stable parameters and grow slowly over many months.
