Arrow How to Help us Help you Identify Algae

This is a note for anyone visiting the Macroalgae forum in the hopes of finding an identification for any invading, new, or old macroalge in their aquariums:

Macroalgae can be very hard to identify. While we (the regulars in this forum) have a good basic (and general) knowledge of the morphology and recognizable structures for several of the green and brown alga, the red macroalgae remain very hard to identify from photographs.

Not only are the distinctions between macroalgae based on the look of their fronds/leaves and coloration, they are also minutely distinguished by the appearance of their reproductive tissue. These structures are not always in existence at all stages of an alga's life. Plus, in the case of red alga, there are literally thousands of species and genera to choose from when attempting an ID.

So far, we dont have any phycologists that roam Reef Central that can weigh in with expert opinions as to true identity. Please keep in mind we do the best we can, but that there will always be a margin of error in this identification game.

That said, here is what we need to have a chance at identifying your alga:

* A clear, crisp photograph

* A description of the texture of your algae (is it brittle? soft? fleshy? does it break easily?)

* A good reference for the size of the algae (try for something in the photograph that shows the scale)

* The location of your live rock or collection spot (Caribbean, South Pacific, Pacific, etc.)

* A description of the growth habit of your alga (growing on rock, on/in the sand, in the water column, etc.)

Links for photographs of algae to compare to yours:

The Algae Page

Algae ID Slideshow

Poppe Images - Algae

AlgaeBase
*Under Search AlgaeBase has a Taxonomy browser and an Image search that can be very helpful.

Beyond the Refugium: A Macroalgae Primer
*See references for good books on macroalgae ID if you are interested in having hard copies in your reef keeping library.

Tree of Life
*Just for fun, this page has an interesting note to help explain the relationships of alga to terrestrial plants.

Note:

Please feel free to add to this list of Algae Identification websites by placing links in replies to this thread.

In case anyone is interested in some non-internet resources..

The classic Marine Plants of the Caribbean (Littler & Littler, 1989) is now basically out of print and extremely hard to find. Luckily, a brand new algae book was just published through HBOI that is a tremendous update. Even though it says it focuses on the IRL system, it covers a LOT of algae that we see volunteer themselves out of Caribbean and Pacific LR.

So.. the two I like for algae ID/algae-nerd reference:

Sprung, J. 2002. Algae: A problem solver guide.

Littler, Littler, & Hanisak. 2008. Submersed Plants of the IRL. HBOI / FAU.

I'm sure there are more books out there that do an amazing job with Algae ID. If you know of a good reference - online or off - feel free to post away!

It maybe algae

Hi Yall,
I sure hope this is the right spot to ask about this item, I have found growing in my about 2 month old set up. About all I can say about it is it kinda soft to the touch. It has what I want to describe as dimples on the end of each umm kinda like alittle red ball. I don't even know if it is an algae. So any help would be cool I will attempt to put a picture on here but never done it before.

Hi guys,
I think rather than starting a thread for a single question, might be better putting it here.

My tank is still on progress (on the making),
I intend to utilize one of my sump chamber as a refugium for macroalgae, and probably plants too.

Yesterday I went to LFS and saw these plants, since it's pretty neat I'm going to get one and put it in my refugium once my tank is completed. Can anyone help with an ID? I'm not sure if it's some sort of halimeda plant.
Thank you.

The first one looks like gracilaria. The second could be galaxaura, but I'm not too sure. What does the second one feel like? There is a wide range of red macros, and many of them look similar. I don't think you will really ever get an exact ID, but you can always get something close.
