stan Posted March 16, 2004 Share Posted March 16, 2004 I got a new piece of LR from the LFS. Marshall Island i believe. Anyways it came with these weird spiky red things attached. I dont believe they're corraline algae. They dont move and are hard to the touch. Any ideas? Link to comment
halmotors Posted March 16, 2004 Share Posted March 16, 2004 I've seen these things on LR before, and I've never noticed them moving or anything like that. From what I can gather, they seem to be some form of hard sponge, or at least a sponge-type creature, or, they could also be a form of coralline...hard to tell without biological testing, and I haven't the foggiest how to do that. I wouldn't worry too much about them. Link to comment
Rene Posted March 16, 2004 Share Posted March 16, 2004 Foraminiferans! Believe it or not those are protozoan animals, just big one. They form a hard, red shell. Harmless and pretty sessile filter-feeders, don't need intentional feeding, prefer shaded areas. Those are probably Homotrema rubrum. I've got them on my LR too. Link to comment
halmotors Posted March 16, 2004 Share Posted March 16, 2004 Well...guess that settles that, eh? Good explanation, Rene. We all learn at least one new thing each day Link to comment
nano-nemo Posted March 16, 2004 Share Posted March 16, 2004 woo hoo, i have them on mine as well and just assumed it was more corraline algae good to know there is a reason i add phytoplankton to feed the live rock Link to comment
stan Posted March 16, 2004 Author Share Posted March 16, 2004 Thanks for the info. I knew you guys wouldn't let me down! You might not be able to make it out from the picture but the one right in the center is four tube-like structures. Interesting. Link to comment
