Chromis is a genus of fish in the family Pomacentridae. While the term damselfish describes a group of marine fish including more than one genus, most damselfish are in the genus Chromis. These fish are popular aquarium pets due to their small size, tolerance for poor water quality, and bright colors, though their lifespans tend to be shorter than other fish.
The Verde Island Passage is a strait that separates the islands of Luzon and Mindoro in the Philippines, connecting the South China Sea with the Tayabas Bay and the Sibuyan Sea beyond. Traditionally, the sea lane has been one of the busiest in the Philippines because it acts as a corridor from the Port of Manila to the Visayas and Mindanao in the south. A network of ferry routes cross the passage and connect the surrounding provinces of Batangas, Marinduque, Occidental Mindoro, Oriental Mindoro and Romblon. The 1.14 million hectare passage is extremely rich in marine biodiversity and has been called "Center of the Center of Marine Shorefish Biodiversity" with various conservation groups pushing for its nomination as a UNESCO World Heritage Site.
