_Caualerpa racemosa_ is a better choice or one of the _Chaetomorpha sp._. _C. racmosa_
dose not go sexually as much as other Caulerpa and going sexually is not a good thing.

Here is some info on _Gracilaria verrucosa _. One problem with this algae is that is sucks
up allot of Iodine, which is probably more a good thing than a bad thing. This also a
great food and many of the food reefers use have/buy has this in it or want it growing in
their tanks
