Sand bed critter I.D.

[Deadmullet]

please... dont know what these little creatures are and if they are bad or good or neither so i was hoping for a little help. I think they are tube worms. if that is even a real creature i dont know but it sounds good

this is my first attempt at posting a pic so here it goes...








this is on my back glass almost to the top of the tank, and has not moved for some time






any help is greatly appreciated

i have no idea what the things in the sand are but i had a few of them once. i got rid of them.

Never seen those, interesting

[Deadmullet]

somebody will know what these little creatures are,

granted i didnt know i had to also take up photography when i decided i wanted a reef tank so my pics arent the greatest

Are the tentacles in the first and third pictures all from one animal? If they are then they're spaghetti worms. They are harmless detritivores.

The worm on the left in the second picture is a chaetopterid or spionid tube worm. Both are harmless filter feeders.

The last picture is a sponge.

[TravesTy]

Hey man, yeah Greenbeans is right... I've seen the worms in my LFS crawling around on everything... and the sponge is a pineapple sponge.. I've got one too... it's harmless and doesn't need anything to thrive...

Here's little something to read about. Your worms are listed towards the bottom.
