    What marine "thing" in your opinion, has become and invasive irritation and what you feel you should warn other reefers to be weary of purchasing?

    Well let's exclude the usual cyanobacteria, hair algae , macro algae etc. Let's stick to corals and inverts.

    Yup, 100's... This is normally the case with all invasive species. Until they become invasive.

    I have an anemone that splits every few weeks and is invading my tank. As beautiful as it is, it is now becoming a pest in the tank as it wants to take over.

    GSP, it grows like weed in my tank. Overgrows everything. If you want to keep it, make sure that the rock is isolated.

    While my mushrooms, Xenia and zoas grow rapidly I don't see them as a weed because I can prune away unwanted ones easily. Aptasia on the other hand is definitely a weed.
    If your anemones are reproducing that much why not share them? I always see people craving anemones.

    That's because you have little nutrients...

    I have the same luck with brown polyps. I just cant get them to grow.

    I have very little nutrients in my tank. The stuff even survives in my sump under an energy saver :eek:

    Brown button polyps.
    Once they spread they can become a big mat.
    I like them. But yes, they can push zoa out of the way.

    Keep them on the rock you want them to be. Do not place them on a big rock where you put other zoa unto as well. Luckily they are relatively slow growers and you can be able to control them. Aiptasia-X also works on them.

    Check my tank pic, I got a nice size colony just off to the left in the bottom of my tank.

    Same with Zoa's...
    They can also take over (I wish) and become a problem (please please do)
    Some guys uses sundail snails on purpose to keep zoa colonies in check...

    also some colonial anemones. If you hop around the rock pools you can find them. They do not have a common mat base like zoa or button, polyps. Individual anemones but loads of them sitting very close to each other forming a carpet.

    Do not add them.

    Slow? I beg to differ that rock you gave me has almost doubled in size & it's what 3 weeks right? That's why I sumped it.

    Cool It is a nice colony I gave you. Got 3 others still going in my frag tank. Will form a nice dense group on that rock.

    As long as you prevent them from climbing onto another rock it will be fine. Unless you want it to spread over. Let it grow over and then you can later cut the first rock loose to split the colony.

    I like those button polyps you have me Riaan. Already seeing some new polyps growing also the xenia. Placed them strategically where they cant spread to much. Thanx again for the corals and crabs. For pests I would also say blue sponge. Look whats happening in the tank we have at Dorry pets.

    Basically all softies, given time and a good stable home, will overgrow the tank. Eventually. Even blue mushrooms.

    Its not an overnight thing.

    Can almost say the same with SPS. Given time and a stable tank, they will overgrow the tank.

    It is up to you to manage the tank.
