Underwater fly trap?

d-ster · 12-18-2006, 12:29 PM

I also have a, coral im guessing, that is in a hard to see spot in my tank I am working on getting a good picture. It looks sort of like a underwater venus fly trap. It opens and closes from time to time its only about the size of the tipof my finger. Its color is a pale green. Any Ideas? The tank I have i bought from a customer of mine from the LFS I worked at. She had it up and running for 6-7 years. Said she nerver did anything to it but feed flakes and add water. I since have added more rock some corals and livestock. It has come a long way.

When she had it:

since Ive had if for 4 months:

im not sure i know what it is,. but if you can manage to get a close up shot we would be more than happy to take a shot at identifying it..

Here's the best I could do:

sorry the second is a bit dark.

Ahhh...
thats a normal feather dusters, they are common hitchihickers.. they are good filter feeders..

you will notice there population increase and decrease based on availible nutrients in the tank..

You are talking about the green object in the middle of the first picture right?

How many kinds of feather dusters are there?

quite a few, certainly more than most folks know, ranging in size from the tiny Spirorbids to the giant Hawaiian dusters.

Hope you don't mind but I took your pic and circled what I think you are talking about.

I have no clue what it is myself.

Thank you that is exactly what I am trying to I.D. Hard to get a picture of it without ripping whole tank apart.

ah.. ok, i was looking at the wrong thing..
that is also a hitchhiker, looks like a mollusk to me, maybe a clam or a scallop.
sorry, i cant be more descriptive than that as im not sure exactly what it is
likely not a problem, but i would look for a more specific ID on it

How can I find out if this is a good thing or a bad thing?

***Rob*** · 12-19-2006, 08:11 PM

here is a good place to start
Bivalvia

you can also google for bivalve hitchiker ID, etc...

I have a few of those attached to my live rock too- they are really cool! They react in the same way as clams do.

I have bunches of them on my rock. Bi-valve is my best ID as well. I've aways presumed that they are fine in my tank.
