Glassfish

Millions of glassfish form shimmering silver clouds inside the Okikawa's holds and between its superstructure, filtering plankton from the water column in a perpetual synchronized swirl. The dense shoals serve as a critical food source for the trevally, barracuda, and snappers that patrol the wreck's perimeter and periodically charge through the baitball. Their translucent bodies and schooling behavior are one of the most photogenic spectacles in Coron diving.
