Genus Haliclona:

Out of the Indo-Pacific several warm colored Sponge genera/species are collected for the trade; my choice picks are the beautiful blue, yellow or purple Halichondria and Haliclona (shown). These two genera comprise hardy (1's), hermatypic finger and encrusting species requiring intense light.

Haliclona vetulina De Laubenfels, Purple Star-Sponge. Red Sea, Indo-Pacific. Made of distinctive channels about its osculae. An aggressive space competitor, displacing almost all sessile invertebrates, including corals. N. Sulawesi and two at Gili Air, Indonesia showing a mollusk being covered and a coral being overgrown.
