Geometric Pygmy Hawkfish description

Just as the name suggests, they actually resemble Hawkfish more than Anthias. They are marked with shapes of different colors without a regular pattern including orange and white, and they have very beautiful green eyes.

They possess an elongated body with a high third dorsal spine which is accompanied by a banner-like flap. They are rare fish, and difficult to get, native to the zones of Cebu.

The Geometric Pygmy Hawkfish is wild and dwells in the reef within the rubble zones and often seen within plate corals.
