best refugium macroalgae

John,
I don't believe it's either of your choices. Bob Fenner mentions something called Nitophyllum which is sometimes called Red Dictyota AKA red Y branch. See if you can find a picture of that.

I don't think that's it.

No that's not it. It does however remind me of this one. The description in Reef Invertebrates sounds just like it.

Where is a good place online to pick up Chaetomorpha? Or if you feel like shipping your trimmings P.M. me, I will pay for shipping and some for your troublel.

Boy i wished you lived closer i've give it to you, its hard for me since i'm disable.

Thanks for the thought. I will probably take cdeakle up on his offer. I will have to wait though since it looks like I will be moving early in August (its about time too).

John, I don't believe it's either of your choices.

That's ok. I'm still sticking with them.

FWIW, the photos I posted show single blades laid out flat (probably separated from a mass of blades like your growth). It is unlikely to find any perfect match between photos and you can see high variability across a genus when you look at the range. Anyone will tell you that many of the macroalgaes (esp. reds and browns) are extremely difficult to positively identify outside of a marine botany lab.

Don't doubt JB for too long. He is normally right. :wink:

Well one thing is for certain. It can't be both of them. When I look at the pictures John posted I would say it looks more like Galaxaria than Gracilaria. The name Gracilaria means slender in latin. There are however (According to Fenner/Calfo) forty species of Gracilaria so maybe John just didn't find the right picture. This stuff doesn't have the V shaped stalk like the picture he posted shows. Calfo/Fenner say Galaxaura is Boneweed and it is heavily calcified. This stuff doesn't feel calcified, but there may be several species of Galaxaria as well. It certainly doesn't look anythin like the picture on p.100 of their Reef Invertebrates book. They also seem to agree more with David than with John when speaking of Dictyota they say "There are yellow-brown, purple and green-hued varities. I was thinking this stuff was rather common and the indentification would be more obvious. Don't write anything in stone just yet.

Well I,m putting my money on Botryoglossum ruprechtianum. Which means grape tongue. Want to bet JB?

I know you are but what am I?

Which is why I only named genus for my guesses.

Gracilaria sp.

That doesn't appear to be universally true for that genus.

Purple ain't red. The purple Dictyota I've seen is distinct.

Purple-ish Dictyota

Don't write anything in stone just yet.

Agreed.

Botryoglossum ruprechtianum

You might be right, but the references say that one is from the California coast. No bets please. But how could this be settled anyway?

John,
It sure looks like the top photo of Gracilaria. You should have posted that one first.
All bets are off. :wink: BTW I think that the red algae in the other thread "Plant or animal" is actually Halymenia psuedofloresia and not H. floridana. Search the Smithsonian site.

Yes, I have already seen the few images on their site. I cannot find an image of H. floridana on the Internet. It looks very much like your plant. But then, there's that variability problem. In most cases it's probably safest to just guess by genus.
