Hey there, I have some live rock in my tank that has long white tentacles that are coming out of some of the holes... They also seem to be creating tubes of sand jutting out in different directions. There are also 2 spots in the sand just outside the entrances on the rock that have the tentecles coming out. They aren't always exposed, and I haven't seen them catching anything or do anything but build the sand tubes. Any idea what they could be? I'll try and get a pic later if my description isn't good enough lol
 
sounds like vermathid (sp.) snails, maybe.
 
forget what they are called but is a sp. of tiny anemone. ive been told they can be a big problem
 
I know that i have skinny bristleworms that are long and white and wave around out of rocks. They are skinny and white, probably juveniles. A pic would make a huge difference though.

That would be Aiptasia.

This is most likely the situation(problem), both Aiptasia and Bristle Worms.

The only way to get rid of Aiptasia is to buy animals that eat them(peppermint shrimp are know to eat aiptasia).

Some fish eat Bristle Worms, but these actually be beneficial if you don't have any corals or have too many of them. Otherwise, you can freshwater dip the live rock and get the worms to fall off.
 
A lot of wrasses will keep bristle worms in check as well.

+1 to biological control being the only real solution to anemone infestation.

You can fight all you want with chemicals, you will just make more smaller ones. Peppermints are the best choice overall I feel for control.
 
Definitely not Aiptasia. Not really sure what it is.
 
Looks like a small bristle worm although I've never seen mine go into the sand - just hang out of rock. We picked up a 6-line wrasse to help with them. He was a great tank mate.
