Barnacle problems?

    A number of years ago I had a 100 gallon reef tank. I had a pretty typical
    setup, wet-dry filter, large home made skimmer, some kind of auxillary
    power-filter & secondary skimmer combo thing hanging on the back, about 5 or
    6 floresent tubes. This was my first venture into reef aquaria. My local
    dealer who was fairly knowledgeable had ordered some live rock for me from
    an unknown (to me) source when I first established the tank. The tank did
    fine for about 6 months, I was successfully keeping mostly fish with a
    couple corals and an anemone. Then I started noticing that these little
    barnacle-like creatures in the tank were increasing in size and number. They
    had a brown or grey hard shell and suction-cup body underneath, and they
    would stick themselves to the rocks and sides of the tank and would be quite
    tough to remove, I usually had to scrape them off or pry them by hand. After
    a few months they started to get out of control, I would spend hours every
    couple of days removing probably hundreds of them, and no matter how many I
    removed there would be plenty more in a couple of days. They would grow and
    then die off by the dozens, so naturally they were causing problems by
    decaying inside the rocks and impossible-to-reach places in the tank. After
    about a year I could no longer keep up with it and it led to unhealthy water
    conditions, a constant unmanagable thick green slime-like algae, and the
    eventual demise of the reef. I moved most of my surviving fish and inverts
    to my other tanks. It worked out okay in the end because I was moving across
    the country and had to sell my larger tanks.

    Anyone else ever have any problems with these barnacle-like things? Any idea
    what they are? I am considering going (very carefully) back into reef
    aquariums (although this time armed with a little more experience,
    knowledge, and a high-tech setup) once I get my new house built and will
    obviously need to have live rock again, but am a little afraid of bringing
    back these nasty little beasts and going through it all over again.

    Thanks,
    Chris

  2. Hi Chris,

    Do a google search for Keyhole Limpets. I had one beautiful one in my tank last
    year that was almost 2" long when it disappeared. Now I have about 20 tiny ones
    about 1/8" long that keep the glass clean. I have a feeling I have enough
    predators in my tank to keep them under control, since they never seem to get
    bigger and the 'mother' hasn't been seen in 6 months.

    What you have are feather dusters, known as Spirorbid's. They are filter feeders but can
    grow to an unsightly problem. They don't do any harm at all and often plague the tank,
    usually on the glass.

  4. Hi Chris,

    Bristle worms are NOT a problem. Like you, I thought they were a real plague.
    I hated seeing them come out during feeding time, and added an Arrow Crab and a
    Longnose Hawkfish just to erradicate these vile beasts.

    Turns out they are good detrivores that clean up all waste, although they are
    constantly blamed for everything evil. <grin> You can see one on my ID page.

    Now I have them in my refugiums as well as my rockwork, and they come out at
    night and clean things up.

    Hmm thats interesting. Wow a lot has changed in 10 years. I've been doing a
    lot of catching up the past couple of days. Funny how things are still
    progressing in this hobby. In 1991 when I first got into reefs, removing the
    biomedia from the (then) required wet/dry would have been considered insane.
    I'm still trying to get used to the idea of having only live rock and a
    protein skimmer as the main filtration system.
