Common name: Dark damsel

General information

The Pacific Gregory, Stegastes fasciolatus, is a species of damselfish that is known for its striking coloration and territorial behavior. It is a small, robust fish with a distinctive pattern of vertical bands on its body. The Pacific Gregory is not as commonly kept as clownfish or other damselfish, but it can be a unique addition to a marine aquarium.

Care

Pacific Gregorys are hardy fish that can adapt to a variety of aquarium conditions. They are known for being territorial, especially when breeding, so it's important to provide them with ample space and hiding places. They can be aggressive towards other fish, particularly smaller or more docile species, so tankmates should be chosen with care. A diet of high-quality marine flakes, pellets, and occasional meaty foods like mysis shrimp will help maintain their health and coloration.

Reproduction

In the wild, Pacific Gregorys are known to be territorial and will vigorously defend their breeding sites. They lay eggs on the substrate, which are then guarded by the male until they hatch. In the aquarium, breeding can be challenging due to their aggressive nature, but providing the right environment with plenty of hiding spaces can encourage spawning behavior.

Habitat

Pacific Gregorys are found in the Indo-Pacific region, from East Africa to the Line Islands, north to southern Japan, and south to New Caledonia. They typically inhabit coral reefs and rocky areas, often establishing territories where they can be quite bold in defending their space against intruders.
