Mushroom corals are known for their ease of care and fast growth, and they can reproduce both sexually and asexually. In the wild, they participate in the annual 'coral mass spawning' event, releasing gametes over a few days after a full moon. In aquariums, sexual reproduction is more sporadic, and asexual reproduction is more common. Mushroom corals can reproduce through budding, pedal laceration, fission, and fragmentation (fragging or propagation). They can also be manually propagated by cutting them at the stalk or base, which results in exponential growth over time. The reproduction rate of mushroom corals depends on their living conditions, including water quality and nutrient availability.

Mushroom corals reproduce both sexually and asexually
Mushroom corals are relatively fast-growing corals that reproduce both sexually and asexually. They are easy to care for and thrive in high-nutrient systems, which accelerates their growth and reproduction.
Sexual reproduction in mushroom corals involves the release of eggs and sperm into the water. This usually occurs during the annual 'coral mass spawning' event, where corals synchronize the release of gametes over a few days after a full moon. Warmer water also seems to trigger sexual reproduction in corals. However, in aquariums, sexual reproduction in mushroom corals is sporadic and less common than asexual reproduction. This is because the conditions in an aquarium differ from those in the wild, and the eggs and larvae produced can become a food source for fish or get sucked up by the filtration system.
Asexual reproduction in mushroom corals can occur through budding, pedal laceration, and fission. During budding, the coral extends a small part of its foot or stalk away from its base, attaching to a rock or substrate. The tissue then detaches from the base, leaving a small piece to grow into a genetically identical mushroom coral. Pedal laceration involves the coral leaving a piece of itself behind as it moves, which then grows into a new individual. Fission occurs when a large mushroom coral splits itself into two or more pieces. Asexual reproduction in mushroom corals can also be facilitated through fragging or propagation, where hobbyists use a scalpel or sharp knife to manually cut the coral into multiple pieces, each of which develops into a new individual. This process is commonly practised to improve aquascaping and create mushroom coral gardens faster.
The choice between sexual and asexual reproduction in mushroom corals depends on various factors, including water quality, temperature, and the presence of suitable living conditions. In general, mushroom corals are adaptable and can reproduce super fast if the conditions are adequate.

They can be manually fragmented, or fragged, to reproduce asexually
Mushroom corals can reproduce both sexually and asexually, although asexual reproduction is more common in captivity. One method of asexual reproduction is fragmentation, or "fragging", which involves manually cutting the coral in half with a scalpel, razor blade, or sharp knife. This process takes advantage of the coral's natural ability to produce clones, allowing hobbyists to quickly create mushroom coral gardens.
Fragging mushroom corals is a simple process. First, select the coral you wish to frag and remove it from the aquarium. It is important to wear safety glasses or goggles as mushroom corals can squirt liquid. Using a sharp cutting tool, cut the coral straight down the middle, directly through its mouth. Each half will then grow into a fully formed, genetically identical mushroom coral.
Another method of asexual reproduction in mushroom corals is budding. In this process, the coral extends a small part of its foot or stalk away from its base, attaching to a rock or substrate. The tissue then detaches from the base, leaving a small piece of its foot or stalk to grow into a new, genetically identical coral. This method can also be facilitated by placing loose rocks around the colony, allowing the coral to spread onto them and then removing the rocks to replace them with new ones.
In addition to asexual reproduction, mushroom corals can also reproduce sexually. This typically occurs during the annual "coral mass spawning" event, where corals synchronize the release of gametes (eggs and sperm) over a few days after a full moon. While this event is well-documented in the wild, it is less regular in aquariums, although warmer water does seem to trigger sexual reproduction. In an aquarium setting, the eggs and larvae produced during sexual reproduction can become a natural food source for fish or be sucked up by the filtration system.

Sexual reproduction is rarer in reef tanks
Mushroom corals are one of the easiest types of soft coral to keep and can reproduce both sexually and asexually. In the wild, mushroom corals participate in the annual 'coral mass spawning' event, where corals synchronize the release of gametes (eggs and sperm) over a few days after a full moon. However, in reef tanks, sexual reproduction is more challenging and less common.
There are several reasons why sexual reproduction is rarer in reef tanks. Firstly, the conditions in an aquarium differ significantly from the wild, making it more difficult for mushroom corals to reproduce sexually. The eggs and larvae produced during sexual reproduction can become a food source for fish in the tank, and if not consumed, they may be sucked up by the filtration system. As a result, reef hobbyists often reduce the powerhead of the filtration system to mitigate this issue.
Additionally, asexual reproduction methods such as budding, pedal laceration, and fission are more commonly observed in reef tanks. Budding involves the coral extending a small part of its foot or stalk away from its base, attaching to a rock or substrate, and then detaching to form a genetically identical clone. Pedal laceration occurs when a piece of the coral is left behind as it moves, which then grows into a new individual. Fission takes place when a large shroom splits itself into two or more pieces. These asexual reproduction methods allow mushroom corals to reproduce rapidly and effectively in the controlled environment of a reef tank.
While sexual reproduction in mushroom corals is a mesmerizing natural phenomenon, the conditions in reef tanks present challenges that make it less likely to occur. The artificial nature of the tank environment, the presence of fish and filtration systems, and the ease of asexual reproduction methods contribute to the rarity of sexual reproduction in these settings. As a result, reef hobbyists often rely on asexual methods or manually intervene through fragging or propagation to facilitate the reproduction of mushroom corals in their tanks.

They can reproduce by budding, laceration, fission, or pedal laceration
Mushroom corals can reproduce both sexually and asexually, although asexual reproduction is more common in reef tanks. In the wild, corals participate in an annual 'coral mass spawning' event, where they synchronize the release of gametes (eggs and sperm) over a few days after a full moon. In aquariums, this event is sporadic, and no regularity has been documented. Warmer water does seem to trigger sexual reproduction in corals.
Mushroom corals can reproduce asexually in four natural ways: budding, laceration, fission, or pedal laceration. During budding, a small part of the coral's foot or stalk extends away from its base. This tissue then attaches to a rock or substrate and detaches from its base, leaving a small piece of its foot or stalk to grow into a fully formed, genetically identical mushroom coral. In laceration, a piece of the coral is left behind as it moves, which then grows into a new coral. Fission involves the coral splitting itself into two when it gets too large. Pedal laceration is similar to budding, as it involves the formation and shedding of a soft tissue particle to create another coral.
These asexual reproduction methods can be facilitated through fragmentation, or "fragging", which involves actively cutting the coral in half with a scalpel or razor blade. This process is commonly used by hobbyists to improve their aquascape and create mushroom coral gardens faster. Fragging can also be done by laying loose rocks around the colony and letting the coral spread onto them. These rocks can then be replaced with new ones once they are covered in coral.
The reproduction process in aquariums will continue throughout the coral's life, and mushroom corals are known for their ability to thrive in high-nutrient systems, which accelerates their growth and reproduction.

Warmer water triggers sexual reproduction
Mushroom corals are one of the easiest types of soft coral to keep and can reproduce both sexually and asexually. While asexual reproduction is more common in reef tanks, sexual reproduction can be triggered by warmer water.
Mushroom corals can reproduce in four natural ways:
- Sexual reproduction: Corals release eggs and sperm into the water. This usually happens during an annual "coral mass spawning" event in the wild, where corals synchronize the release of gametes over a few days after a full moon. In aquariums, this event is sporadic and less predictable.
- Budding: Mushroom corals extend a small part of their foot or stalk away from their coral base. This new tissue then attaches to a rock or substrate, detaching from the original coral to form a fully-formed, genetically identical mushroom coral.
- Pedal laceration: When corals move, they can leave a piece of tissue behind, which will grow into a new coral.
- Fission: When a coral gets large enough, it can split itself into two or more individual corals.
While sexual reproduction in mushroom corals is described as a mesmerizing event, it is less commonly observed in reef tanks. This is because the conditions in aquariums differ significantly from the wild, making it more challenging for mushroom corals to reproduce sexually. Additionally, in aquariums, the eggs and larvae produced during sexual reproduction can become a food source for fish or be sucked up by the filtration system.
However, warmer water temperatures have been identified as a potential trigger for sexual reproduction in corals. Therefore, by creating optimal conditions, such as warmer water and specific pH levels, hobbyists can increase the likelihood of observing sexual reproduction in their mushroom corals.
In contrast, asexual reproduction, or "fragging," is a more common and straightforward method of propagation in reef tanks. This involves cutting the coral in half or at the stalk using a scalpel, razor blade, or sharp knife. Each piece then develops into a separate coral, resulting in exponential growth over time.

Frequently asked questions
The frequency of mushroom coral reproduction depends on how "happy" they are. Adequate conditions, such as ideal water parameters, lighting, flow, and high-nutrient systems, can accelerate their growth and reproduction.
Mushroom corals can reproduce both sexually and asexually, although asexual reproduction through budding, fragmentation, or propagation is more commonly observed in captivity. In the wild, mushroom corals participate in the annual "coral mass spawning" event, where they release gametes (eggs and sperm) after a full moon.
You can manually propagate mushroom corals by cutting them at the stalk or using a scalpel to cut them in half through their mouth. This process, known as fragging, can increase the mushroom coral population in your aquarium.
Mushroom corals have the ability to move within your aquarium, and they may leave baby corals in their wake as they "walk". They can also reproduce by budding, forming a soft tissue particle that is shed off to create a new, genetically identical coral.
