Species Information
Webers Chromis (Chromis weberi) are widely distributed throughout the southern Pacific ocean, where they are found living in near-shore reefs, shallow channels and seaward facing reefs. Webers Chromis have a deeply forked-tail, uniform olive to gray colored body with dark edged scales, a dark bar behind each eye, dark pectoral joints, and dark tail-tips.
Because of their exceptional hardiness, Webers Chromis make a great choice for beginners as well as the more advanced marine hobbyists. Webers Chromis are an active and peaceful species that prefer the mid to top levels of the aquarium; with their constant motion as a school, they will surely add plenty of activity to any reef or FOWLR system.
Although not quite as common as many of their Chromis relatives, they are usually available online and can also be found at local retailers from time to time.
Aquarium Care
Webers Chromis should be provided with a home of at least 30 gallons of water volume and a mixture of open swimming space and live rock and coral formations. Plenty of live rock is important for overall health of tank inhabitants and water quality, but the Webers Chromis will spend most of their time interacting with each other while swimming around in the open as a group; they will utilize live rock for emergency shelter and during the night, but mainly rely on each other for security.
They are very peaceful with other fish species, but will sometimes argue amongst themselves. Despite occasional quarrels Webers Chromis prefer to live in schools of fish, with the more the merrier being the general rule. They can be housed with a wide variety of tank mates as long as they are not highly aggressive or larger predators that will see them as prey.
Feeding & Nutrition
In their natural habitat Webers Chromis are diurnal omnivores; coming out of their shelters at dawn to feed on planktonic surface life, then heading back to their rock cave and crevice shelters at dusk.
In the home aquarium, they are very easy to feed and will readily accept a wide variety of live foods, commercial flake, frozen and freeze-dried foods along with vitamin enriched brine shrimp, mysis shrimp, chopped krill, and blood worms.
They will also accept other prepared meaty marine foods in addition to their natural craving for amphipods, copepods, and other planktonic treats. Feed 1 to 3 times per day.
