Moorish Idol EXPERT ONLY



It is the Moorish Idol is also commonly recognized as in Hawaii by the name of "Kihikihi" meaning "curves," "corners," or "zigzags," and refers to its shape and pattern. It is the sole part in the family Zanclidae and is a closely related to those of Tangs as well as Surgeonfish. The most common species of fish, it is located in all of the Indian Ocean, Red Sea and throughout the tropical Pacific. Wild specimens can grow to seven inches in length however, 4 inches is the most likely to be found in aquariums. It is believed that the Moorish Idol tends to be tranquil. Because of its size, its schooling characteristics, and the need for the space to swim, it needs an aquarium that is at a minimum of 155 gallons. Since its beauty is apparent while swimming, providing ample space is compensated. It's compatible with the majority of species of fish, as well as larger fish, but it shouldn't be kept in a tank with corals or polyps, as they will devour. Small invertebrates are at risk too. The Moorish Idol is a very difficult fish to feed. Live rock with lots of algae and sponges that it could feed can help it to acclimate. Offer a diverse diet consisting of finely chopped fleshy food items such as mysis shrimp, vitamin-rich brine shrimp Spirulina and algae. The diet should be provided frequently throughout the day. Perhaps the most beautiful of all marine fish for many enthusiasts It is also among the hardest fish to keep as it's so challenging to feed. For anyone other than the most skilled hobbyist they prefer to admire it in the ocean or at an aquarium for public viewing rather than in a personal tank.

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.
