Caulerpa on LR

[Moonstream]

So I just got new LR and noticed some Caulerpa on it. The stuff has in the 2 days in my tank taken off! I am afriaid it may be the invasive kind, and also don't want it to take over my tank! Is this bad? Are there any fish that can live in a 29 gallon that can keep this stuff in check? I may move it to my 6 gallon, and let it grow like mad. That will be nice, and I can move the current LR in there to the 29 gallon. Or I could leave it in there.
If I were to keep the algae in the 6 gallon, what fish could go in there? Oh by the way, the 6 gallon is an eclipse, and has a 10 gallon light on top, with a 15 watt bulb.

All kinds of caulerpa can grow fairly fast, some faster than others. If you were planning on keeping this tank as a reef tank, then you may have a problem. In a tank that small, I can't think of any fish offhand that you could keep in there that would eat it. There are however nudibranches that will feed only on caulerpa, so they may be your best bet if you want to get rid of it.

I think an urchin should make a dent in it

 

[Moonstream]

cool, an urchin it is. What kind of urchin should I get? The tank is only 29 gallons, so I am guessing a long spine is out of the question?

 

[Moonstream]

also, when would I add the urchin?

I have grape culepra that come in on a piece of Florida live rock. At first, I liked it, but as I am now adding corals, the stuff is no longer appreciated. Other than pruning it with my hands, does any one have a method to better control or eliminate this stuff?
