If you’re an aquarium enthusiast with a reef tank, you’re likely familiar with the challenge of controlling algae growth. While some algae are necessary for a healthy ecosystem, excessive growth can cause a host of problems, from competing with coral for resources to reducing oxygen levels in the tank.
One effective way to control algae growth in a reef tank is by introducing saltwater algae-eating fish. In this article, we’ll highlight the top 7 saltwater algae-eating fish species that are suitable for a reef tank.
Criteria for Selecting the Best Saltwater Algae-Eating Fish for a Reef Tank
Before we dive into the top 10 saltwater algae-eating fish for a reef tank, let’s briefly discuss the criteria for selecting the best species:
Compatibility: It’s important to choose fish that are compatible with other fish in the tank to avoid aggression and territorial behavior.
Diet: Some algae-eating fish are more selective in their diet, while others are more opportunistic. It’s important to choose fish that will eat the specific types of algae in your tank.
Effectiveness: Some fish are more effective at controlling algae growth than others, so it’s important to choose species that are known to be good at this task.
Behavior: Algae-eating fish come in a variety of shapes and sizes, with different behaviors and temperaments. It’s important to choose fish that will fit well in your tank and won’t harm other fish or coral.
Top 7 Saltwater Algae Eating Fish for Your Reef Tank
Tangs are a popular choice for reef tanks and are known for their bright colors and active personalities. There are many different types of Tangs, but some of the most popular include the Yellow Tang, Blue Tang, and Sailfin Tang. Tangs are effective at keeping your tank clean by eating a variety of algae types, including hair algae, diatoms, and cyanobacteria.
However, they do have some drawbacks. Tangs can be aggressive towards other fish, so it’s important to make sure you have enough space in your tank for them to establish their own territory. Additionally, Tangs require a larger tank than some of the other algae-eating fish on this list, so keep that in mind if you’re considering adding them to your tank.
Blennies are another popular choice for reef tanks and are known for their interesting personalities and unique looks. There are many different types of Blennies, but some of the most popular include the Lawnmower Blenny, Bicolor Blenny, and Starry Blenny. Blennies are effective at keeping your tank clean by eating hair algae and other types of algae that grow on the rocks in your tank.
They are generally peaceful and get along well with other fish, making them a good choice for community tanks. However, it’s important to note that Blennies can be territorial and may become aggressive towards other Blennies or fish that are similar in appearance.
For reef aquariums, a rabbitfish are a fantastic option because of their distinctive appearances and fascinating personalities. There are many distinct varieties of rabbitfish, but the Foxface rabbitfish, Magnificient rabbitfish, and Spotted rabbitfish are three of the most well-known.

They are a fantastic choice for community tanks because they are often calm and get along with other fish. It’s crucial to keep in mind, though, that Rabbitfish can be aggressive and can get territorial when it comes to other Rabbitfish or fish with a similar appearance.

Surgeonfish are generally peaceful and can be kept in pairs or small groups, but it’s important to only keep one Surgeonfish per tank, as they can become aggressive towards each other.
Angelfish are a beautiful addition to a reef tank, with their vibrant colors and unique body shape. These fish are omnivorous, meaning that they eat both algae and small invertebrates. Some popular species of Angelfish include the Coral Beauty Angelfish and the Flame Angelfish.
They also add a beautiful pop of color to your tank. However, it’s important to note that some Angels can be aggressive toward other fish, so it’s important to monitor them closely. Additionally, Angels can grow quite large, so make sure you have enough space in your tank to accommodate them.
Gobies are a type of small, peaceful saltwater fish that are a great addition to a reef tank. These fish are bottom-dwellers and are known for their unique body shape and behaviors. Some popular species of Gobies include the Green Mandarin Goby, the Yellow Clown Goby, and the Neon Goby.
Gobies are good at keeping your aquarium clean since they consume the algae that grow on the rocks and on the sand in your tank. They are a fantastic choice for community tanks because they are often calm and get along with other fish. It’s crucial to keep in mind that gobies can be territorial and can act aggressively towards other gobies or fish that resemble them.
Wrasse is well-liked in reef tanks due to their distinct personalities and stunning colors. The Six Line Wrasse, Yellow Coris Wrasse, and Melanurus Wrasse are a few of the more well-known Wrasse species out of the many that exist.
Wrasse is an efficient tank cleaner since they consume hair algae and other kinds of algae that flourish on the rocks in your aquarium. They are a fantastic choice for community tanks because they are often calm and get along with other fish. Since certain Wrasse can be hostile to other fish, it’s necessary to keep an eye on them because of this.
Adding algae-eating fish to your reef tank is a critical step in keeping your tank healthy and clean. There are many different types of algae-eating fish to choose from, and each has its own unique pros and cons.
It’s important to do your research before adding any fish to your tank to ensure they are compatible with your current setup and will thrive in your tank. By selecting the right mix of algae-eating fish, you can help ensure the long-term health and success of your reef tank.
