What are these? (pics)
 

Ok, thought I'd finally get around to trying to ID some of the stuff in my tank. I have some other things as well that I'm not sure about, but I'll get some pictures of them later.

I like the look of this. Some kind of green algea maybe... almost seems to have tiny leaves.

This thing looks cool, but I have a feeling it may not be desirable... Over the last several months it has grown in size. On a side note what is the small whitish thing directly to the left of it?

I'm pretty sure that the first one is some type of Caulerpa just because of the way it is growing out. From my own personal experiences with caulerpa, you should remove it while it is still localized. It is known to benefit the tank as a nutrient export (ie. phosphates), but it will eventually get out of hand and become overwhelm your tank. Additionally, it is very difficult to remove once it has spread that much because the roots get into rock crevices and can't really be removed.

The second one is a botton polyp, they are kinda similar ot zoos.

Hope this helps.

agreed

the second pic is button polyp scientific name is protopalythoa in case youre interested

or as I like to call them... "Fugly Polyps" :razz:

Alright, thanks for the replies everyone. I think I'll remove the Caulerpa to keep it from taking over.

BTW your rock looks SWEET.

The white thing in the second pic is probably some kind of aptasia. Don't want them in your tank, either. There have been lots of threads on aptasia control. Just do a search for it for ways to get rid of it.

What size tank are you running?

I would keep the calurpa and get a foxface or some tangs in the future. I think it adds diversity to the tank, when kept under control.

Many of us grow calurpa in seperate tanks as a water filter, and to feed our fish.
