Mushroom corals are a fascinating species that can move and spread very quickly. They are known for their ability to 'walk during the night, searching for more suitable locations within their environment. This movement is facilitated by the inflation and deflation of their tissues, allowing them to detach from their base and use water flow to reach new spots. Mushroom corals are also capable of asexual reproduction by breaking off and cloning themselves, leading to the creation of new coral colonies. With a preference for low-to-moderate lighting and water flow, these corals are easy to care for and can add a vibrant touch to any aquarium. However, their rapid spread can sometimes be undesirable, requiring population control to maintain balance.

Mushroom corals can move and spread by 'walking'
Mushroom corals are known for their ability to move and spread by "walking" across the ocean floor or aquarium floor in search of more suitable living conditions. This phenomenon, often observed by aquarium hobbyists, showcases the unique locomotion capabilities of these soft corals.
Mushroom corals, or corallimorphs, belong to the family Fungiidae and are solitary animals. They are characterised by their lack of a skeleton, a feature that distinguishes them from other types of corals. This absence of a rigid structure grants mushroom corals a degree of flexibility and mobility not commonly associated with corals.
The process of movement in mushroom corals is a fascinating one. They can inflate and deflate their tissues to move, or in the case of larger specimens, they may detach from their base and use water flow to float to a new location. Once they find a desirable spot, they securely attach themselves to a rock or substrate. Smaller mushroom corals tend to move faster than larger ones, and those with a smooth bottom and granular costae can pull themselves along more efficiently.
The walking behaviour of mushroom corals is driven by their search for optimal living conditions. In aquariums, they may move to find more favourable lighting and water flow conditions. They prefer lower light environments and can stretch upward in the water column, creating their iconic mushroom-like appearance. This behaviour is not unique to a specific species but is characteristic of the entire group under lower lighting conditions.
In addition to their walking ability, mushroom corals can also spread by reproduction. They can reproduce both sexually and asexually, with asexual reproduction being more common in home aquariums. Asexual reproduction can occur through laceration, where they leave behind pieces of coral that grow into new individuals, fission, where they split into smaller parts, and budding, where they form and shed soft tissue particles.

They can also reproduce asexually, leaving clones behind as they move
Mushroom corals are known to move around aquariums in search of more favourable conditions. They can move in any direction and can use water flow to float to their desired location. They can also crawl, although this is a slower process. As they move, they leave behind tiny pieces of coral, which can grow into clones of the original coral. This process is called mushroom pedal laceration. It is a natural form of asexual reproduction, also known as budding, where a small piece of tissue buds from the mushroom's foot. This is one of four ways in which mushroom corals reproduce and spread. The other three methods are sexual reproduction, fission, and laceration.
Mushroom corals are soft corals that do not produce a hard skeleton. They are found in most temperate to tropical marine ecosystems and are especially prevalent in Australia, Tonga, Indonesia, and the Caribbean. They are commonly kept in reef aquariums due to their bright colours and ease of care. They are also inexpensive and can be placed in the quieter and darker corners of the tank.
Mushroom corals are known to move unpredictably and slowly, usually during the night when the aquarium lights are off. They can inflate and deflate their tissues to move, and larger mushrooms can detach from their base and float to a new location. Once they have found a suitable spot, they attach themselves securely to a rock or substrate.
Mushroom corals are solitary animals from the family Fungiidae and are capable of benthic locomotion in the ocean and in reef aquariums. They are known to be peaceful and do not have stinging sweeper tentacles. They can be fed most fish and coral foods, and they will happily accept meaty foods.

They can reproduce sexually, by releasing eggs and sperm into the water
Mushroom corals are fascinating creatures that can reproduce both sexually and asexually. While asexual reproduction is more common in home aquariums, they also have the ability to reproduce sexually. This occurs when the mushroom coral releases eggs and sperm into the water.
Mushroom corals, also known as Corallimorpharia, are a diverse group of soft corals that can be found in temperate to tropical marine ecosystems. They are characterised by their lack of a hard skeleton and their ability to thrive in low light and low flow environments. This makes them ideal inhabitants in mixed species tanks, as they can coexist peacefully with fish and other corals.
The reproductive process of releasing eggs and sperm into the water is just one of several ways in which mushroom corals can reproduce sexually. This method of reproduction allows for genetic diversity and the potential for new and unique characteristics to emerge within the species.
In addition to their ability to reproduce sexually, mushroom corals can also reproduce asexually through laceration, fission, and budding. Laceration occurs when a piece of the coral breaks off and clones itself to create a new colony. Fission happens when a large coral splits into two or more smaller corals. Budding involves the formation and shedding of soft tissue particles that develop into new individuals.
The reproductive strategies of mushroom corals contribute to their ability to spread and populate new areas. In fact, mushroom corals can spread very quickly and are often found in large colonies, covering rocks and other structures, including other corals. As a result, population control may be necessary to maintain balance in their ecosystems.

They thrive in low-light, nutrient-rich environments
Mushroom corals are a fascinating species that can thrive in low-light, nutrient-rich environments. They are known for their ability to adapt and survive in various conditions, making them a popular choice for aquarium enthusiasts. Here are some key points to understand about their preference for low-light habitats and their ability to spread:
Low-Light Environments
Mushroom corals, or Corallimorpharia, are unique in that they do not require much light and can thrive in low to moderate light conditions. In fact, exposure to high light can be detrimental, as it may bleach and damage their delicate tissues. In their natural habitat, mushroom corals are often found in the lower regions of the ocean, where light intensity is reduced. This preference for low-light conditions is also advantageous in aquariums, as it allows them to add colour and interest to darker corners that other corals may struggle to inhabit.
Nutrient-Rich Environments
Mushroom corals are opportunistic feeders and will happily accept most fish and coral foods. They obtain nutrients from their symbiotic relationship with zooxanthellae, small photosynthetic organisms that provide them with sugars. Additionally, each polyp has a mouth, enabling them to ingest small meaty foods. This adaptability in feeding contributes to their success in nutrient-rich environments.
Spreading and Movement
Mushroom corals have a remarkable ability to spread and populate their surroundings. They can reproduce both sexually and asexually, with asexual reproduction being more common in home aquariums. During asexual reproduction, they can spread through laceration, fission, and budding. In laceration, they leave behind pieces of coral as they move, which then grow into new individuals. Fission occurs when a large mushroom coral splits into smaller ones, and budding involves forming and shedding soft tissue particles.
The movement of mushroom corals is another factor contributing to their spread. Unlike most other corals, mushroom corals can move and will relocate to more favourable areas within their environment. They achieve movement by inflating and deflating their tissues, crawling, or detaching from their base and using water flow to float to a new location. This ability to move and spread makes mushroom corals a dynamic presence in any aquarium.
Care Considerations
While mushroom corals are generally easy to care for, their ability to spread rapidly can be a consideration for aquarium management. Population control may be necessary to maintain balance within the aquarium ecosystem. Regular fragging, or propagation, can help manage their growth and create new colonies. Additionally, providing them with their preferred lighting and flow conditions can reduce their need to move and spread uncontrollably.

They are soft corals and do not produce a hard skeleton
Mushroom corals are soft corals that do not produce a hard skeleton. Unlike other corals, they lack the remnants of skeletons, known as sclerites, which are tiny bone shards embedded in coral tissue. This absence of a skeleton leads to their classification as "False corals". Mushroom corals are part of the Corallimoprharians taxonomic order, specifically the Corallimorpharia order, which contains nearly 50 species. They are also referred to as \"mushroom anemones\" due to their resemblance to anemones, particularly in their lack of long, retractable feeding tentacles.
Mushroom corals are known for their ability to move, a phenomenon often called "walking". They can move in any direction and are capable of benthic locomotion in the ocean and reef aquariums. This movement is facilitated by inflating and deflating their tissues, crawling, or detaching from their base and using water flow to float to a new location. Their movement is often driven by the search for more suitable lighting and flow conditions, as they thrive in low-to-moderate light and low-to-moderate water flow.
The ability of mushroom corals to reproduce both sexually and asexually contributes to their rapid spread. Asexual reproduction is the most common method in home aquariums, occurring through budding, laceration, fission, and propagation with a scalpel. During budding, a small piece of tissue is budded from the mushroom's foot. Laceration involves leaving behind a piece of coral during movement, which then grows into a new coral. Fission takes place when a large mushroom splits into smaller parts. These methods of asexual reproduction, along with their quick spread, make mushroom corals ideal for covering rocks and other structures in aquariums.
Mushroom corals are a popular choice for reef aquariums due to their ease of care, variety of colours, and ability to thrive in low-light, nutrient-rich environments. They are typically found in the lower regions of the tank, adding colour and interest to darker corners that other corals may struggle to inhabit.

Frequently asked questions
Mushroom corals can spread very quickly and are often found in large colonies, covering rocks and other structures, including other corals. They can reproduce both sexually and asexually.
Mushroom corals can reproduce in four different ways: sexually releasing egg and sperm into the water; laceration, where they leave a piece behind that will grow into a new one when they move; fission, where the mushroom splits itself; and budding, where it forms a soft tissue particle and sheds it off to create another.
Mushroom corals thrive in low-flow environments. They are also sensitive to light, so exposing them to high light can bleach and damage them. Therefore, controlling the flow and light conditions in the aquarium can help manage the spread of mushroom corals.
