How to get rid of bryopsis plumosa

Among the different pests that we can have in our marine aquarium, there is the Bryopsis algae, which although it may be attractive at first sight, the reality is that due to its rapid expansion, it is undoubtedly one of the pests that we must eradicate as soon as possible.

How does it reproduce?

This type of algae can reproduce sexually (through the union of male and female gametes), as well as asexually, by releasing spores that are released when trying to pull it out; in fact, this is the most common form of reproduction.

One of the characteristics that makes this a difficult pest is that it is able to survive even with very low levels of nutrients, and is even capable of spreading to areas with less lighting within the aquarium.

In addition to the above, it seems that Bryopsis does not have a reliable predator, it seems that herbivorous organisms do not like it very much, although there are some aquarists who report having had success with organisms such as sea urchins (tripneustes gratilla), emerald crabs (mithraculus sculpted), or even Foxface fish (Siganus vulpinus), the reality is that sometimes they eat it, other times they totally ignore it.

Bryopsis and corals

In itself, this algae is dangerous, because of how invasive it is, it invades the corals in such a way that it suffocates them to the point of drowning them; and since it reproduces very quickly, we run the risk of losing corals if it is not attended to in time, which is why we need to attack it as soon as we see it in our tanks. The following are some images of tanks with this plague.
