Black Bar Chromis



The Black Bar Chromis originated from reefs located in the Western Pacific, and is typically found in branches of coral heads. They are yellow to tan in appearance and have a distinctive vertical black bar at the point where the body joins the tail. Set up the fish with a 30 gallon or more aquarium that has plenty of live rock available for the chromis fish to hide in. They prefer being in groups of at least six. They tend to be peaceful, except when they live alone. This Black Bar Chrromis can be described as an omnivore that should be fed both meaty and plant-based food items. Feed frozen mysis and vitamin-enriched brine shrimp, as well as high-quality flake foods. Approximate Purchase Size: Small: Less than 3/4"; Medium: 3/4" to 1-1/4"; Large: 1-1/4" to 2"

Helpful Questions From Clients
Frequently Asked Questions
Is hiring a professional necessary to set up a saltwater aquarium?

As a general rule, a larger custom aquarium might require installation by a professional. However, a kit from our online fish store is relatively affordable and beginner friendly. That means you should have no problem setting it up yourself.

Which saltwater aquarium fish should you choose when starting out?

Consider a yellow tang fish. This popular saltwater aquarium fish does a great job of coexisting with other types of fish you’ll find in our online fish store.

How does a saltwater aquarium differ from a freshwater one?

Saltwater aquariums require a bit more maintenance and monitoring than freshwater tanks. Different fish require different levels of salinity, pH tolerances, and temperature requirements. They also require specialized pumps, filters, and other equipment that can handle salt. We can guide you through everything you need to know to set up a healthy, thriving reef tank.

Do fish in a saltwater aquarium swim in a school?

That depends on the species. However, if it’s a fish that swims in a school in the wild, they’ll do the same in an aquarium. Some fish that swim in schools include the green and blue chromis, cardinalfish, and dartfish, for example. When ordering from an online fish store, make sure you do your research on how specific fish species behave to ensure they’ll school (or at least coexist) with your current fish.

Is the effort required to maintain a saltwater aquarium worth it?

Yes! Many aquarists dream of owning thriving saltwater aquariums. You have a tiny piece of the ocean in your home, featuring magical and exotic fish that can only survive in saltwater.
