    Hi,

    I notice some strange looking "toadstool" like "polyps" starting to grow on my live rock.
    They are dark red in color with either black or bright red spots on them.

    They start off as little red blotches on the rock and over a span of three to six weeks develop to a size of about 5mm on a 3mm high stem.

    The older ones tend to fade to a faded red color with split edges.

    I may just add that my tank have been running for about five years now and I have not added anything new like rocks corals etc lately. About two months ago I upgraded my sump and tankstand and therefore had to empty out the display tank completely. I kept the substrate and live rocks as is an refilled with most of the old water. I also transferred the substrate from my old sump to the new one. So, as you can see very little chance that these "polyp things" could get into my tank as hitchhikers.

    Is this a pest or should I be proud of my new inhabitants :blush:

    Thanks Tremayn for the info

    Looks like you spot on with the ID. I do some further research just to confirm.
    Damn !!!!! Now that I've got and ID I need to figure out how to get rid of them.:(

    Just a pity its a nuisance algae cos it kinda looked nice with the red spots and all.....

    Are they bad? I have them for about 3 months now and they haven't been a problem. Did anyone else experience any problems with these? I know they are not as bad as the green bubble algae

    After closer inspection I've realized that there are quite a few more of these small red bubble algae on the live rock in my tank and when taking into account how fast they spread, I figured that this might become a problem soon. So, they have to go asap and I will be going shopping tomorrow for "exterminators" ;-)
