I have some other weird thing growing in my tank again. ID?

[SCIronMike]

Here's a pic fellas. It just appeared and it expands and contracts. Doesn't move at all. Thanks

If it's actually contracting my guess is a colonial tunicate. If it's totally sessile then sponge would be more likely. Look at the pics in the links below and see if any of them are a close match - normally most colonial tunicates aren't so drab but who knows

Neat animals, if they are thriving then you must be doing something right. Also they are actually proto-chordates so a link between invertebrates and vertebrates.

Hmmmm....... interesting. But this actually has more of a "honeycomb" texture. Not hexagons, but it's "holey". It's hard to describe what it looks like and it's REALLY hard to take a good pic of.

Where did you get your rock? Sure seems to be full of life!

I have the exact same thing on a piece of my rock. It's been there for like 8 months. I have no clue what it is either.

yes Id vote for some kind of colonial or cryptic tunicate. I have them too Mike and they seem to appear in proportion to addition of Dt's and/or infaunal activity of the system. Mine are just like your picture, and they appear on the rear of the reef wall and not in the front where the lights are for some reason..not sure if there is any correlation here but thats what they seem to prefer. Are yours in a well-lit region of the tank?

Pretty sure thats a sponge, but I don't have my books with me.

Well, I'll get another picture soon.......... it has tripled in size in one week.

if its trippled in size thats a sign of a tank well off to a good start. i too belive its a tucinite not a sponge. the sponge wouldent appear to expand and contract.

$10 says its a sponge!

hi.
I throw in $10 with shaman and brandon for trunicate...

Mike, use one of your dissecting microscope and see if you can tell them apart. Sponge is a lot more simplier than trunicate in cellular structure.

 

[Anonymous]

So if I win I get $30?

 

[O P Ing]

hi.
Dan, I don't know if shaman and brandon want to have anything to do with the money portion of it... I don't speak for them, you know.

I used to have this stuff growing all over my tank. It has a very open lattice like structure of tubes- not really tunicate like at all. Grows real fast.

If we're voting, I'm voting for sponge.
If we're betting, I've got $10 Canadian!

SCIronMike,
Did you take a picture of my rock and post it as your own :mrgreen: ? I have that same thing with those red thingies (can't remember their name right now) right next to it also. Hmmm...

[Carpentersreef]

red thingies = foraminiferans
sponge = well, I'm looking for a photo link....

Mitch :wink:

Yeah, what are those red thingies? And for proof that it is my aquarium :lol:

For the weird thing in question above the torch coral and to the right of the colt coral

Whats your camera doing hiding out in that cave in the middle of your tank 8O ?!?!? :wink: Nice looking tank! How long has it been setup? (Sorry I'm not much help in identifying that spongy looking thing )
