Zoas' Stinging Mushrooms: A Dangerous Encounter

do zoas sting mushrooms

While it is unclear whether mushrooms sting zoas, it is known that corals are always battling for space and will release toxins to damage other corals that are too close to them. Some corals directly sting their neighbours, while others use chemical warfare to deter other corals from coming too close. In the case of mushrooms and zoas, it seems that the mushrooms will eventually take over the zoas, either by outcompeting them or by releasing toxins that kill them. However, some people suggest that the two types of coral can coexist peacefully if given enough space to grow and expand.

Zoas and mushrooms can exist together in a saltwater aquarium

One source suggests that the mushrooms and zoas will release toxins to damage each other, a process known as allelopathy. However, another source claims that they have had mushrooms and zoas intermingled with no ill effects. In this case, the mushrooms and zoas were lower in the tank, which may have contributed to their peaceful coexistence.

If you are concerned about the mushrooms and zoas in your tank, you can try moving the mushroom to a different location. This may involve breaking part of the rock they are both attached to, or simply moving the mushroom if it is still attached to a frag plug. It is generally advised to minimise the disturbance to coral, as moving it can do more harm than good. However, if the mushroom is still small and attached to a plug, it may be possible to move it without causing damage.

It is worth noting that some people choose to isolate all mushrooms from other coral to avoid any potential issues. Proper acclimation is also important when introducing new coral to your tank. It is recommended to minimise the hours of light exposure per day to properly acclimate the coral to the new lighting conditions.

Zoas and mushrooms don't sting but may compete for space

Zoas and mushrooms do not sting but they may compete for space. While stinging does occur among certain types of corals, it is not a concern when keeping zoas and mushrooms together. However, this does not mean that they will coexist peacefully. Both zoas and mushrooms require space to grow and expand, and they may come into conflict as a result.

In a reef tank, it is common for corals to engage in a form of "chemical warfare" or "allelopathy", where they release toxins to deter other corals from encroaching on their territory. This can create a natural barrier that prevents different types of corals from growing too close to each other. While zoas and mushrooms may not directly sting each other, they can still negatively impact each other through the release of these toxins.

In some cases, the competition for space between zoas and mushrooms can lead to one outcompeting the other. Mushrooms are known to grow and spread rapidly, and they may end up covering the zoas. This can result in the zoas closing up or struggling to open fully. While it is not advisable to move coral frequently, in such cases, relocating the mushroom to a separate rock or area of the tank may be necessary to prevent harm to the zoas.

It is important to monitor the situation closely and be prepared to take action if one starts to dominate the other. While it is generally recommended to provide sufficient space for corals to grow and avoid placing them too close together, the specific spacing required can vary between different types of corals and may depend on their genus. Additionally, some corals are more aggressive than others, and it can be challenging to predict which species will overrun another, even within the same family.

In summary, while zoas and mushrooms do not sting, their competition for space can lead to challenges in maintaining a harmonious reef tank. Reef keepers should be prepared to intervene if one starts to negatively impact the other, whether through the release of toxins or physical encroachment. Providing adequate space and carefully considering the placement of different corals can help mitigate these issues.

Zoas and mushrooms can be separated by moving one to another rock

In a saltwater aquarium, mushrooms and zoas often compete for space and can release toxins to damage each other. This process is known as allelopathy, where a coral releases toxins to harm another coral that is too close to it. Some corals may also directly sting their neighbors, although mushrooms and zoas are not known to sting.

If you notice that your mushrooms are covering your zoas and preventing them from opening fully, you can try moving the mushroom to another rock. It is important to do this carefully to avoid damaging the mushroom. One method is to use a "scoopula" to dig out the rock under the mushroom's foot and then provide it with rubble to reattach to in a low-flow area. Another method is to cut the mushroom as close to the base as possible with sharp scissors. If you want to prevent the mushroom from regrowing, you can smother the remaining tissue with epoxy.

After moving the mushroom, you can place the rock lower in the tank and reduce the hours of light exposure per day to help the zoas acclimate to their new environment. It may take a day or two for the zoas to fully open again. By providing each species with their own space, you can help them thrive and reduce the competition for resources.

Overall, while zoas and mushrooms can coexist in an aquarium, they may occasionally need some assistance to ensure their long-term survival and well-being. By following the advice and techniques outlined above, you can successfully separate zoas and mushrooms by moving one to another rock.

Zoas and mushrooms may release toxins to deter each other

In a reef ecosystem, corals are known to compete for space, and this competition can sometimes lead to the release of toxins or stinging behaviour. While zoas and mushrooms may not directly sting each other, they can still impact each other's behaviour and growth patterns. For example, if a mushroom is covering zoas, it may cause the zoas to close up or exhibit reduced opening behaviour.

In some cases, the toxins released by corals can be harmful to other corals nearby. However, it is important to note that not all soft corals possess well-developed stings, and their ability to engage in chemical warfare can vary depending on their genus. Additionally, the toxins produced by soft corals are organic and can be effectively removed from the water using activated carbon.

To mitigate potential issues, it is recommended to provide adequate growing space for corals and avoid placing them too close together. By doing so, the chances of corals releasing toxins or stinging each other can be reduced. However, it is worth noting that even with proper spacing, some corals may still exhibit aggressive behaviour towards each other.

In situations where zoas and mushrooms are in close proximity and negatively affecting each other, relocating one or both of them may be necessary. However, it is important to approach this with caution, as moving coral can sometimes do more harm than good. It is a delicate balance to maintain the health and well-being of all the corals in a reef tank.

Zoas can move away if bothered by mushrooms

Zoas and mushrooms are both types of coral. While some corals can sting, it seems that zoas and mushrooms do not. One source states that most softies don't sting but they do like a bit of growing room. As a result, they exude poisons (allopathy) to deter other corals from coming too close and to create some growing room. Another source corroborates this, stating that mushrooms and zoa don't really sting.

However, this does not mean that zoas and mushrooms can coexist peacefully. While they may not sting each other, they will compete for space. One source notes that a reef is like a war zone. Some don't know it but they are always battling for space. In the case of zoas and mushrooms, it seems that the mushroom will usually be victorious in this battle for space, as mushrooms will expand and split, taking over its area.

Therefore, if a mushroom is bothering a zoa by encroaching on its space, it may be necessary to intervene and move the mushroom to a different location. Several sources recommend doing this, with one source noting that after they moved the mushroom and set the rock lower in the tank, their zoas seemed happier and were "sprawled out even bigger than before". Another source recommends giving the mushroom its own rock.

However, it is important to note that moving coral can be risky and may do more harm than good. One source recommends that the corals will figure their own shit out, I’m not gonna bother them. Additionally, if the mushroom is still attached to a frag plug, moving it may kill it.
