Different Types of Moss and Algae that Grows on Rocks in a Saltwater Aquarium
Learn about the different types of algae that grow in saltwater tanks including green algae, blue algae, red algae, and blue-green algae.
There are four types of algae that are commonly seen in saltwater aquariums.
Green Algae
Many saltwater aquarium owners are probably familiar with green algae. It commonly grows on live rocks, gravel, and even along the glass of the aquarium tank. Green algae, which is scientifically known as Chlorophyta, appears in many forms, depending on the species. Aquarists should identify moss and algae on live rock in saltwater aquarium so that invasive species can be halted before they overwhelm the coral.
Caulerpa algae is one type of green algae that is found in saltwater aquariums. They have long strands that run horizontally and attach to various substrait with rootlike hairs. The Feather variety of Caulerpa algae feature feather-like green leaves, while the Grape variety has clusters of small, round green balls. The Razor variety of Caulerpa is considered extremely invasive. It latches onto rocks and coral with razor-like blades.
There are over 6,000 species of red algae, which is scientifically known as Rhodophyta. The most common type of red algae that is introduced to saltwater aquariums is Coralline algae. It can appear green, red, purple, pink, or white. The coloration is dependent on the amout of pigment present in the algae. It is considered a benefit to have Coralline algae since it livens the appearance of the aquarium.
Coralline algae usually remains in one area of the aquarium. Some aquarists prefer the algae to spread to other coral or rocks. The usually method to accomplish this involves scraping away bits of algae from its current area and allowing the particles to spread and settle in other areas of the tank. The fliters are usually turned off during this process.
Brown algae contains a pigment that blocks color-producing pigments, resulting in a beige or yellow-brown to dark brown color. The presence of brown algae usually indicates several problems. A lack of adequate lighting will promote the growth of brown algae. An over abundance of silicates in the water, as well as a lack of oxygen, contribute to an overpopulation of brown algae. Most species of brown algae are considered seaweed. Brown algae is classified as Phaeophyta.
Blue-green algae, also known as Cyanobacteria, is actually a type of bacteria that grows on tank walls and on the surfaces of rocks and coral. Aquarists commonly identify moss and algae on live rock in saltwater aquarium by color. Blue-green algae typically appears as a brownish-red slime. They feed on organic waste and discharge toxins into the water. Removal of blue-green algae is difficult, due to its consistency. The best way to remove the bacteria is by using a suction tube and changing the water.
