Torch coral is an aggressive species that will sting and kill other corals that come too close. It is photosynthetic and requires a decent amount of light to survive. Mushrooms, on the other hand, can also kill or inhibit the growth of other corals without physical contact. While there are reports of torch coral killing fish, it is unclear whether the coral caused the death of the fish or simply ate a dead fish that floated its way. There is also a mention of a clown fish killing a torch coral.

Torch coral is photosynthetic and requires light to survive
Torch coral (Euphyllia) is a photosynthetic species, meaning it relies on light for survival. While it can survive without being fed, feeding this coral boosts its health and growth rate. It gets its energy from light through the symbiotic zooxanthellae algae living inside its tissues, which convert light energy into sugar. As such, torch coral requires moderate to high lighting levels to maintain its health and
In addition to lighting, torch coral requires moderate to high water flow and stable water parameters, including a temperature range of 75-82°F and a pH level of 8.1-8.4. It is important to monitor and maintain these stable water parameters to promote coral growth. Torch coral should be placed in a low to moderate flow area with adequate space to allow its long, flowing tentacles to extend fully without harming other coral or fish.
Torch coral is an aggressive species that will sting and kill anything that gets too close, including other corals that invade its space. Therefore, it is important to give it enough space to grow and thrive without harming other corals in the aquarium. They can be moderately easy to care for, but they do require specific care to thrive, such as regular feedings of smaller meaty foods like brine shrimp or mysis shrimp.
Torch coral is a popular species of Large Polyp Stony (LPS) coral that is commonly found in the Indo-Pacific region. It comes in various vibrant colors, including green, pink, red, and yellow, adding a beautiful pop of colour to any reef aquarium. With the correct conditions, torch coral can be a stunning and relatively easy addition to a reef tank.

Mushrooms can kill or inhibit the growth of corals without direct contact
Mushrooms can extend during the day to catch the sun and move, and this can be problematic for torch coral. For example, a reef enthusiast moved their torch coral within an inch or two of three large mushrooms, and within a few days, the coral had crashed to the point of no recovery. This was likely due to the mushrooms' influence, as they can kill or hinder the growth of other corals without touching them.
Torch coral requires specific care and conditions to thrive. It is photosynthetic and relies on light for survival, so placement in an aquarium is crucial. It also requires a decent amount of light, up to 250 par, and benefits from variable flow from multiple directions. As an aggressive species, it needs adequate space to grow and thrive without harming other corals.
While torch coral can defend itself with its long, stinging tentacles, it is vulnerable to certain pests and predators, such as bristle worms, crabs, and snails, which can damage its tissue and lead to stress or death. Additionally, it is susceptible to brown jelly disease, a bacterial infection that can be fatal and requires prompt treatment.
It is worth noting that the term "mushrooms" can also refer to certain types of coral, as mentioned in some forums. In these contexts, "mushroom coral" or "mushroom-shaped coral" is used to describe the shape and structure of the coral, which resembles a mushroom cap. However, in this case, we are considering the potential impact of mushrooms (fungi) on coral.

Torch coral is an aggressive species that will sting and kill other corals
Torch coral, also known as Trumpet Coral due to its appearance, is a species of Large Polyp Stony (LPS) coral. It is commonly found in the Indo-Pacific region and is a popular choice for reef keepers, especially beginners, due to its hardiness and ease of care. Torch coral is photosynthetic, relying on light for survival, and can be fed with small pieces of meaty foods.
However, one of the challenges of keeping torch coral is its aggressive nature. It is a highly territorial species that will protect its space by stinging and killing neighbouring corals that come too close. Its long sweeper tentacles contain nematocysts, which can damage or kill other corals and more delicate tank mates. Therefore, it is crucial to provide sufficient space between torch coral and other corals in the aquarium.
The aggressive behaviour of torch coral is a natural adaptation to gain a competitive advantage in the battle for space on the reef. In home aquariums, this behaviour can be managed by providing adequate spacing and choosing compatible tank mates. It is recommended to avoid placing torch corals near aggressive or large-polyped stony (LPS) corals, such as hammer or frogspawn corals. Instead, they can coexist peacefully with certain fish species, such as clownfish, damselfish, gobies, and other small, peaceful fish.
To ensure the health and longevity of torch coral, proper acclimation and stable water conditions are essential. Torch corals require moderate to high water flow and moderate to high lighting to thrive. Regular water testing and maintenance are crucial to maintaining optimal water parameters. Additionally, it is important to be cautious of their stinging tentacles when handling torch coral to avoid any harm to oneself or the coral.
In summary, torch coral is an aggressive species that will sting and kill other corals that invade its territory. Proper care and management of their environment, including spacing and compatible tank mates, are key to preventing conflict and ensuring the well-being of all aquarium inhabitants.

Torch coral is vulnerable to pests and predators, such as crabs and snails
Torch coral is a species of Large Polyp Stony (LPS) coral commonly found in the Indo-Pacific region. It is also known as the Trumpet Coral due to its appearance. While torch coral can be moderately easy to care for, it is vulnerable to certain pests and predators.
One of the most common pests that can affect torch coral is the vermetid snail. These snails can irritate the coral and, if left unchecked, can multiply quickly and become a persistent problem. Other pests that can harm torch coral include bristle worms and crabs. These creatures can damage the coral's tissue, causing stress or even death.
To prevent pests and predators from harming torch coral, it is crucial to maintain good tank hygiene. Regular cleaning and removal of debris and uneaten food are essential. Quarantining new coral before introducing it to the tank can also help prevent the introduction of pests. If pests or predators are already present, they should be removed manually or treated with a suitable solution, such as Bayer 2-way.
In addition to pests and predators, torch coral is also susceptible to territorial issues with other corals. It is an aggressive species that will protect its territory by killing any other corals that invade its space. It is important to provide sufficient space between torch corals and other corals to prevent conflict.
Overall, while torch coral can be vulnerable to certain pests and predators, such as crabs and snails, proper care and maintenance can help ensure the coral's health and reduce the risk of infestation or predation.

Some corals will eat dead fish, leading people to think they killed them
Torch coral is an aggressive species that will protect its territory by killing any other corals that invade its space. It has long, stinging tentacles that can damage or kill neighbouring corals. Therefore, it is important to give it enough space to grow and thrive without harming other corals in the aquarium. While torch coral can sting and kill other corals, it is unlikely to kill fish. Some people have speculated that torch coral can kill fish, but this is not true. In fact, it is more likely that a dead fish will be eaten by the coral.
Torch coral is photosynthetic, meaning it relies on light to survive. It is typically kept in a tank with variable flow that is not directly by a pump. It can be fed with small pieces of meaty foods, such as brine shrimp or mysis shrimp. However, it also gets much of its nutrition from the zooxanthellae algae that live inside its tissues.
While torch coral is generally safe for fish, there are other types of corals that are known to eat fish. For example, elegance and rhizos are fish-eating corals that can consume dead fish. It is important to be aware of the different types of corals and their dietary habits before introducing them into an aquarium.
In addition to fish-eating corals, there are also mushrooms that can be harmful to corals. Some mushrooms can extend quite a bit during the day to catch the most sun and can inhibit the growth of other corals, even without physical contact. It is important to carefully research and identify the different species of mushrooms and corals before placing them in close proximity to each other.
Overall, while torch coral is an aggressive species that can harm other corals, it is unlikely to kill fish. It is important to provide it with the proper care and conditions, including adequate space and lighting, to ensure its health and the health of the surrounding ecosystem.
