Reef tank maintenance is essential to the health and well-being of your aquarium ecosystem. One key element in maintaining a balanced environment is having a proper clean-up crew. A reef tank clean up crew consists of various organisms that help keep your tank clean by performing specific tasks such as consuming waste, algae, and excess food.
Let’s explore the roles of each member of your reef tank clean up crew in more detail.
Snails
Snails are an essential part of any reef cleanup crew. Here’s why:
Grazers
Snails are natural grazers, meaning they consume algae and other small organisms that grow on rocks, glass, and equipment in your tank. Having a healthy population of snails will help keep algae growth under control and prevent it from overtaking your tank.
Detritivores
In addition to consuming algae, snails also feed on organic waste and uneaten food that accumulates on the substrate of your tank. This helps keep the bottom of your tank clean and prevents harmful bacteria from forming.
They Aerate the Sand Bed
Many species of snails burrow and move through the sand bed, which helps aerate it. This is beneficial because it prevents pockets of anaerobic bacteria from forming, which can produce toxic gases harmful to your tank inhabitants.
Hermit Crabs
Hermit crabs are another popular choice for your reef tank clean up crew. Here’s how they contribute:
Scavengers
Hermit crabs are scavengers and will consume any leftover food or organic waste on the substrate. They also help keep the sand bed aerated by digging and sifting through it.
Algae Eaters
Aquarium algae control is crucial, and hermit crabs can help with that too. They consume various types of algae, including hair algae, green algae, and diatoms.
Shell Cleaners
As hermit crabs grow, they will molt and shed their old shell. This process creates a calcium-rich snack for your coral and other tank inhabitants. It also ensures that the crab always has a properly fitting shell to protect itself.
Shrimp
Shrimp are another popular member of the reef tank clean up crew. Here’s how they contribute:
Scavengers
Like snails and hermit crabs, shrimp are scavengers and will consume any leftover food or organic waste on the substrate. They have a keen sense of smell and can find hidden pockets of waste to clean.
Sand Sifters
Many species of shrimp, such as the popular sand-sifting shrimp, are excellent at aerating the sand bed. They dig and sift through the sand, helping to prevent harmful bacteria build-up.
Pest Control
Shrimp are also helpful in controlling pest populations in your tank. They feed on small pests like bristle worms, pyramid snails, and flatworms that can harm coral and other tank inhabitants.
Starfish
Starfish are not as common in reef tank clean up crews, but they can still play an essential role. Here’s how:
Detritivores
Starfish feed on organic waste and debris that accumulates on the substrate. They can also help keep your sand bed aerated by sifting through it.
Algae Eaters
Some species of starfish are excellent algae eaters, consuming various types of nuisance algae like hair algae and cyanobacteria.
Sand Stirrers
Certain species of starfish use their arms to stir up and aerate the sand bed, similar to shrimp and hermit crabs. This helps prevent harmful bacteria build-up and keeps the sand bed healthy.
Copepods and Amphipods
Copepods and amphipods are tiny crustaceans that are essential for a healthy reef tank. Here’s why:
Food Source
Many fish and invertebrate species, such as mandarin dragonets and seahorses, rely on copepods and amphipods as their primary food source. Having a thriving population of these organisms ensures that your tank inhabitants stay well-fed.
Nutrient Cycling
Copepods and amphipods also aid in nutrient cycling by consuming waste, excess food, and dead plant matter. This helps keep the water quality in check and prevents harmful spikes in ammonia and nitrate levels.
Natural Cleanup Crew
These tiny organisms are natural scavengers, constantly cleaning up your tank’s substrate and live rock. They also consume algae, preventing it from overgrowing and causing issues in the tank.
Brittle and Serpent Starfish
Brittle and serpent starfish are another less common addition to a reef tank clean up crew. Here’s how they contribute:
Detritivores
Like other starfish, brittle and serpent starfish feed on organic waste and debris that accumulates on the substrate.
Sand Stirrers
These types of starfish use their long arms to stir up and aerate the sand bed, which helps prevent anaerobic bacteria build-up.
Pest Control
Brittle and serpent starfish can also help control pest populations in your tank by consuming small invertebrates like bristle worms and pyramid snails.
Bristle Worms
Bristleworms are a commonly found organism in reef tanks, and although they may not be the most visually appealing, they play an essential role in the clean-up crew. Here’s how:
Detritivores
As their name suggests, bristleworms eat detritus, or organic waste, that accumulates on the substrate. They also consume any uneaten food and dead plant matter.
Sand Sifters
These worms help aerate the sand bed by burrowing and sifting through it.
Pest Control
Although some species of bristle worms can become pests themselves if allowed to be overpopulated, they can also help control other pest populations in your tank. This includes flatworms and small snails.
Urchins
Urchins are another less common member of the reef tank clean up crew, but they can still have a significant impact. Here’s how:
Algae Eaters
Urchins are excellent algae eaters, consuming various types of nuisance algae like hair algae and cyanobacteria.
Detritivores
They also feed on organic waste and debris that accumulates on the substrate, helping to keep the bottom of your tank clean.
Sand Stirrers
Similar to other sand-sifting organisms, urchins help aerate the sand bed by sifting through it.
