TJ_Burton Posted July 6, 2012 Share Posted July 6, 2012 Wondering if anyone has any info on this macro algae. This is my first experience with it - popped up all on its own and grows rapidly. Thankfully its more on the ornamental side Link to comment

TeflonTomDosh Posted July 6, 2012 Share Posted July 6, 2012 sounds like a John Maloney deal. Ask him Link to comment
albertthiel Posted July 6, 2012 Share Posted July 6, 2012 Well, Hopefully this is enough cause I can't get any closer with my iPhone Looks like Galaxaura acuminata or G. rugosa to me ... are the branches of it somewhat flattened and say from 1 to may 2 or 3 mm wide ? Is it in a shaded area as that is where this algae grows best ... It is usually pink to red and can grow to about 15 or so cm in length ... Does that sort of fit the algae ? Albert Link to comment

Albert It is currently under a Radion, not shaded, and grows like crazy while producing an iridescent/metllic coloration. The branches are tubular (oblong not perfectly circular) and segmented, and have a jelly-like feel to them. I took a look at G. acuminata & rugosa, but I don't believe it is either. I could be wrong, but they are not a close enough match for me to be able to confirm them. Link to comment

Thanks I'll have a look in one of my other reference books when I get back to the house Albert Link to comment
albertthiel Posted July 6, 2012 Share Posted July 6, 2012 Looks like nemastoma to me Could be ReHype but not sure, I am waiting get back home and will check in some of my ref bus Link to comment
albertthiel Posted July 7, 2012 Share Posted July 7, 2012 Well, Hopefully this is enough cause I can't get any closer with my iPhone Did you look up Nemastoma and what I posted and does that seem to be what that red algae is ? Please let us know. Thanks ........... Albert Link to comment
albertthiel Posted July 8, 2012 Share Posted July 8, 2012 Appears to be a Laurencia sp. Could be Laurencia succisa as that one is iridescent and can be red or even green ... I have however not seen any comments back from the original poster Albert Link to comment
TJ_Burton Posted July 9, 2012 Author Share Posted July 9, 2012 Neither Laurencia and Nemastoma seem to fit. I wish I could just send you guys some to look at in person, but I am in Canada and that likely won't fly. Also, the piece in the close up shot is no larger than a fingernail in size. Link to comment

Also, the piece in the close up shot is no larger than a fingernail in size. How does it feel to the touch ... is it calcified or does it feel slippery, or what impression do you get when you rub over one of the branches ... I have now looked in several reference books and although some come close I have not found an exact match yet so I am wondering if it is some time of semi-calcareous type algae in the Rhodophyta group. Please let me know. Thanks Albert Link to comment

Please let me know. Thanks Albert Certainly not a calcareous algae. It is smooth/slimey and has a gelly/rubbery texture similar to that of various caulerpa species. It has some elasticity to it as well when tearing off a piece. Link to comment

Take a look at this page and maybe you recognize ... possibly Galaxaura ? http://marineplantbook.com/marineplantbookredalgae.htm Albert Link to comment
atoll Posted July 12, 2012 Share Posted July 12, 2012 This algae resembles Champia parvula in form from my book "Marine Plants of the Caribbean" however it is described in it as being yellowish to pale pink. Link to comment

Also I posted 4 pics of the algae you have on my thread (see sig) and hopefully someone there will come up with an ID as so far we have not been able to find an ID that matches what you say you have. Is this cluster of algae growing ? Albert Link to comment
keydiver Posted July 13, 2012 Share Posted July 13, 2012 I agree with GRmoore that it is a species of laurencia. If you'd be willing, I'd love to get my hands on some. Link to comment

Did you see the post on my thread where the algae ID is suggested as Laurencia ... several pictures of it where posted but by now it many be visible only a few pages back from the last page Albert Link to comment
TJ_Burton Posted July 17, 2012 Author Share Posted July 17, 2012 If I had to pin it to one, I'd say Chondria sp. is the closest. Link to comment

I will try to get a better photo of it in tank to post up. Link to comment
TJ_Burton Posted July 17, 2012 Author Share Posted July 17, 2012 Best I can do with my iPhone. You may notice a different species of algae in the back, but it is not the same, just grows close by. Link to comment
keydiver Posted July 17, 2012 Share Posted July 17, 2012 From the closeup, it actually doesn't look like a chondria species. Chondria is less gelatinous and more flattened. The color matches but the growth pattern doesn't. I'm stumped Link to comment
