BumbleBeeJBG Posted September 3, 2009 Share Posted September 3, 2009 Que eso? Found these on a rock, tank is mid-cycle. They appear to have grown in an area with no light as evidenced by the lack of coralline on that part of the rock. They've at least kept their color in my tank with no light and going through an ammonia cycle. Link to comment
Jacobnano Posted September 3, 2009 Share Posted September 3, 2009 I was thinking Foraminiferans, I guess I could be wrong. Link to comment
BumbleBeeJBG Posted September 3, 2009 Author Share Posted September 3, 2009 Sponges can branch like that? Link to comment
The Nomad Posted September 3, 2009 Share Posted September 3, 2009 I was thinking Foraminiferans... +1 Link to comment
BumbleBeeJBG Posted September 3, 2009 Author Share Posted September 3, 2009 So, completely harmless and cool looking and hope that they grow? Link to comment
lakshwadeep Posted September 4, 2009 Share Posted September 4, 2009 yes (foraminiferans, not sponges) Link to comment
johnmaloney Posted September 7, 2009 Share Posted September 7, 2009 oh well, cant win them all. lots of branching sponges though, (just about any shape you can imagine really) i thought Foraminiferans more mobile, so much for wikipedia I was thinking Diplastrella megastellata (sponge): Forams have a calcified shell, so you can test it for hardness vs. "spongeness". but see shimek: http://reefkeeping.com/issues/2003-07/rs/index.php Link to comment
Justind823 Posted September 7, 2009 Share Posted September 7, 2009 I have a bunch of those in my tank. Since my cycle I cannot see that they have grown at all. Link to comment
lakshwadeep Posted September 9, 2009 Share Posted September 9, 2009 Foraminiferans will have very thin/clear "hairs" (pseudopodia) on the ends of their branches. +1 to checking for hardness or sponginess. Link to comment
johnmaloney Posted September 9, 2009 Share Posted September 9, 2009 inverts are a strange lot aren't they? I wonder how many forams i have seen diving and had no idea... Link to comment
lakshwadeep Posted September 10, 2009 Share Posted September 10, 2009 I read that there is some caribbean beach which has "pink" sand because of accumulated foraminiferan skeletons. Link to comment
johnmaloney Posted September 10, 2009 Share Posted September 10, 2009 i havent seen that... you got me all interested in forams now, probably spend a good deal of this weekends travels trying to spot some. not to hijack, but do they reproduce in tanks? the shimek article says short lived, but doesnt mention reproduction.

NotTheFace Posted September 10, 2009 Share Posted September 10, 2009 It's too bad they don't get much bigger than the OP's pic. I like them. Link to comment
