How about an identification thread for marine algae? Member Keeshcarm had asked about one and I thought I would give it a shot. It is not the intent of this thread to give advice on the algae, just to help to identify it. While the species shown may not be the species you have it will give you an indication of the look of the algae and possible help you to search for the exact species you have. Be aware that you may never be able to get down to the exact species but hopefully this I.D. thread will help you to identify the genus and possibly family and therefore the care needed.
Whenever we set up a tank it seems that there are at least a few different algae that hitch along with the live rock. Some good some invasive but always part of the biota out in the vastness of the ocean we are trying to replicate. There are reefers that will do anything to get their hands on as many and varied types they can do add to their displays, then others that will do anything to keep it out. Won’t take up sides here but will try to go out to the net and pick up some photos and descriptions of some of the ones we see more often than not. I will also attempt to give credit for the pictures in a way that does not go against any of the rules of for posting here. So here we go!!
Lets start off with one of the more common and invasive of the algae we see, that being Caulerpa sp.
A quick note on the law…….
United States Law: It is illegal to import or transport Caulerpa taxifolia aquarium strain across state lines including internet sale (Federal Noxious Weed Act, 1999; and Federal Plant Protection Act, 2000). I suggest you do some more research on the laws regarding the transport and sale of Caulerpa sp. Especially our California friends.
Caulerpa racemosa var. peltata
