The blue vase sponges, Niphates digitalis that we get are anywhere from about 2-5 inches high. This variety of sponge does well in aquariums but needs to be handled carefully and kept under water at all times. It is a very common sponge but it is a very delicate shipper that is why we like to ship smaller pieces of about ~2inches .

This is the coolest sponge. I have several of Ken’s sponges and this is my favorite. Looks just like the picture.
