hey, try saying that even once...



But yeah, so what Bev has is a funky red alga that occupies outer reef slopes? cool.

Tried saying it THREE times, and still can't get it right

Also IDed another red macroalgae, Gracilaria abbottiana, in my reef from that page....



And some coralline, Mastophora pacifica, too....



Still have one more MA that needs ID. It looks like Amansia rhodantha, but not quite....



That is a cool page for macroaglae ID

Gads! I'm on a macroalgae roll

Used to have lots of Codium edule until the tank change, from.....

Have some Peyssonnelia sp. ....

And from here....

We have a rock encrusted with this Peyssonnelia sp. ....




Now, back to the blob. Quote from Anthony Calfo...

It looks like it could be a Nemastoma species (see page 104 of my Reef Invertebrates book plus text entry).

Anybody have this book for reference?

Here's a pic of a Nemastoma sp. from here....

But other photos from algaebase.org do not look anything like our blob. Very confusing

WOW!! I am totally stunned with surprise and respect for Charles Delbeek

He saw the videos I posted to Aquarium Fish Magazine, and sent me an email from Hawaii where he's vacationing. He says when he gets back to his library at home, he's going to try to ID the genus of our red blob. Like, WOW, man

Thanks, Vic, for the great suggestion

He may be on vacation but he actually lives there since he's the curator of the Waikiki Aquarium (or one of them). Anyhow that's cool that you'll get a response from him.

After a bit of back and forth with Charles Delbeek, this is what he's concluded about our red blob....

It is virtually impossible to accurately ID macroalgae from photos of whole specimens. Some species even have completely different growth forms in different parts of their life cycle (e.g. Aspharagopsis (sp??)). Anyone who does any sort of macroalgae taxonomic work can only ID to species using a microscope and even then it is not 100% for certain they will get the right species. So my advice is to just call it Predaea sp., you will not be able to ID to species without a taxonomic key and a microscope and several years experience.

Seems pretty harmless to me and easily controlled. Enjoy it while you can, many macroalgae are seasonal.

So, Predaea sp. it is
