What is Hair Algae?

Defining Hair Algae

Hair algae, also called “serratula,” “thread algae,” or “blanket weed,” encompasses several types of filamentous algae. It grows in threads or strands, resembling hair and clinging to plants, decorations, and other surfaces. Hair algae can be green, brown, or even black, and it usually thrives in aquariums with excessive nutrients, especially iron and ammonia.

Ghost Shrimp: A Natural Cleaner

When it comes to hair algae control, ghost shrimp can lend a helping hand. These tiny crustaceans feast on hair algae and other organic material, making them a perfect addition to a well-maintained aquarium. Ghost shrimp can trim hair algae from plants and ornaments, cleaning without causing damage.

Ghost Shrimp Behavior and Diet

Ghost shrimp are primarily scavengers, and they enjoy feasting on algae, detritus, and leftover fish food. They’re helpful in controlling the hair algae problem in your tank, even though it might not be their favorite meal. Be aware that they may need additional food sources, depending on the severity of your algae problem.

Understanding Ghost Shrimp

Appearance and Size

Ghost shrimp, or Glass shrimp, are small, transparent shrimp with a maximum size of about 1.5 inches. Their clear body makes them difficult to observe in the tank, but it’s also a fascinating feature that appeals to many aquarists.

Compatibility and Tank Requirements

Ghost shrimp are compatible with most peaceful fish species and thrive in well-established, freshwater aquariums. Think along the lines of small fish like tetras, rasboras, and guppies. Aggressive or larger fish, such as cichlids and some types of barbs, are not suitable tankmates, as they could attack or eat the shrimp. Ghost shrimp prefer temperatures between 65 and 75°F, a pH of 7.0 to 8.0, and a tank size of at least 5 gallons with plenty of hiding spots.

Combating Hair Algae

Besides incorporating ghost shrimp into your aquarium, you can try several other tactics to control the hair algae problem:

Improve Water Quality

Regular maintenance, including frequent water changes, gravel vacuuming, and filter upkeep, is essential for water quality. Furthermore, keeping nitrate levels under control and using tap water treatment can further reduce available nutrients for algae.

Reduce Excess Lighting

Hair algae often grow in areas with excessive light. Controlling the amount of light and duration is an essential factor in discouraging hair algae growth.

Introduce Other Algae Eaters

In addition to ghost shrimp, consider introducing other algae eaters to your tank, such as Otto Catfish, Nerite snails, and Amano shrimp

Limit Nutrients

Controlling the amount of food you provide and feeding your fish moderately can help keep the excess nutrients in check. Overfeeding is a common contributor to hair algae growth.

Add Live Plants

Live aquatic plants compete with algae for nutrients in the water, potentially limiting hair algae growth. Fast-growing plants are especially useful in this regard.
