    What is this stuff?

    I have this green plant/algae/weed growing on one of my rocks in my nano tank. I wasn't sure what it was, so I thought I'd ask here.

    The picture is blurry, but the plant is green and branches out sort of like a fern. It looks nice, but I don't want it to take over my tank.

    So does anybody know what it is?

    not too sure from the picture.. but looks like a species of caulerpa.
    odds are it will take over the tank if left untreated. try to get the usual critters that can eat it.. crabs and tangs, but at worse, trim as much. if it still doesn't go.. remove the rock and either let it dry completely and scrub it off.. or add it to your sump. caulerpa is a good filter, but has the possibility of going asexual if cut or eaten.. so most of us usually try and remove it completely and in one shot. replace this algea with a non dangerous species like cheatomorpha sp. or the like.

    hope this helps.
    but get a good identification first, cauz its always nice not to kill things if at all possible.. it could make for a very nice species tank.

    moving.. so temporarily out of SW :b8:
    planning next tank, possibly 60x30x20 on 2x plasma.

    Well this is the first time that I am going to tell someone not to take Liv's advice. :b13:

    Since you said it is in your nano tank I wouldn't get a tang for control as suggested.

    But a better picture would help with a more positive ID of what it is.
