Caring for these beautiful creatures

Can you really keep Caulerpa in the main tank?

I have always kept Caulerpa in the Rose tank. It helps to keep the water clean and also adds natural color to the reef.

It has never gone asexual so I have had no problem with it.
 It does start to grow around the sides and up the front of the tank so it is pulled from the places that I don't want it. But I have never removed any of it from the back of the tank.

The Yellow Tang loves it and keeps it mowed to an even height along the back.

Just a word of caution however. It WILL  go asexual by turning white and fouling the tank so be careful when using it in a large tank.

I keep a close eye on mine for any signs of the whitening of it and would pull it immediately if I saw the signs. But after 4 years in the tank it has never done it. Here is a  picture of it.
Sorry for the quality of the first picture, many on my site are old and taken with an old digital camera.

Here are some new pictures of Feather Caulerpa that I now keep in my tank.
I have never known it to go asexual in the tanks so I keep it in all of them, not only for looks
but to help keep the water clear.
And I just love the looks of it.
