Sailfin Tang, Desjardini



Desjardini Sailfin Tang, also called the Indian Ocean Sailfin Tang, Desjardin's Sailfin, also known as Red Sea Sailfin Tang, is light to dark gray with small freckles on the nose and yellow spots around the stomach. The body features several different sizes of vertical yellow stripes, with intricate patterns between the stripes on the front. It also has an emerald tail that is blue that is white with freckles. Its appearance is able to expand in size by lifting or lowering its large dorsal and anal fins. A 180-gallon or bigger aquarium is required to give ample space for swimming. It can be aggressive toward its own species and other conspecifics sometimes but is peaceful toward other fish, so you should only keep one fish in tanks that are very large. It is a fan of filamentous algae. While Tangs can eat meaty foods as do others in aquariums, it's essential that they get ample amounts of seaweed that is marine-based and algae. This can strengthen the immune system and decrease aggression, and improve overall health. Provide dried seaweed that is tied to a rock, or the veggie clip, and feed them at least three times a week. Sea Veggies, Seaweed Salad, and Ocean Nutrition are all ideal products that are easy to prepare. Please note that the Small Juvenile model of Desjardini Tang may not have white spots on their fins or the body and is identical in appearance to the Sailfin Tang. But as they age spots are likely to develop along with the bold striping that covers the body and fins.

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.
