What Does Coral Bleaching Look Like in Hawaii?
24 Jan, 2020
from CORAL contributor Bruce Carlson
Potter’s Angelfish (Centropyge potteri), like other pygmy angelfishes, is always on the move, and it takes time and patience to photograph. Alternatively, you could just set a GoPro camera and tiny tripod on a rock and wait.
This January (2020), my partner Marj Awai and I recorded a single Potter’s Angelfish on the reef in Honaunau Bay, on the west coast of the Island of Hawai’i. The original video is about five minutes long, but I’ve edited it to show just those moments when the angelfish appears. It feeds on algae growing on the rocks.
Watch the video to the end: The last scene shows the devastation to the fields of finger Porites corals killed during severe coral bleaching events the past few years. There are enough living nubs that the coral will likely grow back in a few years, provided there are no more bleaching events, or the corals acclimate to higher seawater temperatures.
Fishbase: Centropyge potteri (Jordan & Metz, 1912)
Distribution: Eastern Central Pacific: Johnston and Hawaiian Islands.
Size: Max length : 10.0 cm TL male/unsexed (4 inches)
