Silverstripe Chromis

Chromis alta

The Silverstripe Chromis is a small reef fish found in the Eastern Pacific, particularly around Mexico, the Galapagos Islands, and occasionally Cocos Island. Divers can spot this species at depths ranging from 30 to 150 meters, where it inhabits coral and rocky reefs. It has a compressed body shape with a maximum length of 13 cm. Identifying features include its dorsal fins, which consist of 13 spines and 12 to 14 soft rays, and its anal fins with 2 spines and 12 to 13 soft rays. This species primarily feeds on plankton, making it a key part of the reef's trophic dynamics. During breeding, the Silverstripe Chromis exhibits distinct pairing behavior. It is oviparous, with eggs that adhere to the substrate. Males play a crucial role in guarding and aerating the eggs until they hatch. Divers encountering the Silverstripe Chromis will find them to be harmless and non-migratory. The IUCN lists this species as Least Concern. Observing their breeding behavior can be particularly interesting, as males are actively involved in the care of their eggs.
