andy Posted October 2, 2006 Share Posted October 2, 2006 Any idea what the mostly-algae-covered tendrils are? I've got several of them here and there, some on live rock, etc. Quote Link to comment Share on other sites More sharing options...
Guest Mbeef61 Posted October 2, 2006 Share Posted October 2, 2006 i think maybe a sponge...if they really are algae covered then my guess is they are like the white sponge i have sticking out of my zoo colony...doesnt do any harm and you can prune them but they come back...

nu2reef-n Posted October 2, 2006 Share Posted October 2, 2006 I'm not so sure it's a sponge. I get some growths like that now and then, never that long. My sailfin tang spends his time grazing the rocks, so not much escapes his hungry little mouth. I think it is more likely some kind of macro algae.

Michael7979 Posted October 2, 2006 Share Posted October 2, 2006 I would think it's some form of macro also, but what exactly it is I don't know. Quote Link to comment Share on other sites More sharing options...
Nyles Posted October 2, 2006 Share Posted October 2, 2006 Dunno the exact name, but my tangs eat them after they get about 1" long, then they regrow and when they get to about 1" again they mow them down again. Quote Link to comment Share on other sites More sharing options...

izzypop Posted October 2, 2006 Share Posted October 2, 2006 I've seen the green slime algea in most of your pics from overdosing amino acids/reef booster things like that. Especially if it is a new tank under a year old. Don't know what it is called. Quote Link to comment Share on other sites More sharing options...
siskiou Posted October 2, 2006 Share Posted October 2, 2006 The tendrils, if normally white like the tips, look like a boring sponge I once had in my 20G. It was pretty invasive, but vanished after a couple of years. Quote Link to comment Share on other sites More sharing options...
Guest Mbeef61 Posted October 3, 2006 Share Posted October 3, 2006 good yes another sponge vote...i swear thats the same sponge i have except algae covered so it looks green not white...yeah i agree can be very invasive but doesnt sting or anything.

WAVES Posted October 3, 2006 Share Posted October 3, 2006 Im with Roy although I didnt know what it is, but look at a google search for neomeris: http://images.google.com/images?sourceid=navclient&aq=Neomeris&ie=UTF-8&rls=GGLD,GGLD:2004-52,GGLD:en&q=Neomeris&sa=N&tab=wi Nice job Roy, Quote Link to comment Share on other sites More sharing options...
Guest Mbeef61 Posted October 3, 2006 Share Posted October 3, 2006 yeah that was my nex t closest guess...but if you look into those species they are calcifiying algae and they obtain a hard calcium carbonate shell....my sponge do-hicky never got ridgid or anything it just blew around.

andy Posted October 3, 2006 Author Share Posted October 3, 2006 If you look closely at those pictures of neomeris, you'll see that it has a white stalk with green tips. This critter of mine is the reverse, with a green stalk and a whitish tip. I pulled a few samples out last night and took a closer look; they do appear to be sponges, with green algae growing on the surface. The texture of the strands was very different from a calcerous macroalgae like halimedia, which is tough and almost brittle -- these were, well... spongy Also, to pretty much close the deal, I found a couple of strands growing on the backs of some live rock, out of direct lighting. These strands didn't have a coat of green algae, and were pretty clearly growing out of an encrusting sponge colony. I'll try and get some pictures later, just for kicks. Boring Sponges can be bad news for corals. I cut those strands off of the Tubipora, and will keep and eye out in case they grow back.
