anyone help?is it a pest or a good guy?

[vulkum]

this little guy showed up out near the bottom of my live rock and i saw a blue legged hermit messing with him. i had checked some of the post and the closest thing i came up with was something called PLANERIA or something like that. he's sortaa triangular and purple on the top with little hairs. the bottom sorta looks like a shell and is almost translucent. should i 86 him before he disappears back in the rock or what? i hate to kill anything that comes out of my live rock, but i don't want an infestation of them later. any help would be great. vulkum

i've posted a few pics of the culprit to see if anyone can identify!

I've never heard of a flatworm with hairs.

i don't think this is any worm! it sorta looks like a large grain of rice. i posted pics if someone can make out what it is please let me know. thanks vulkum

Your URL asks me for a password so I can't view the pic. It still sounds like a flatworm. They are harmless but can quickly multiply to plague proportions.

How big is it? Maybe it's a stomatella

thanks for the help this lot of rock i got has been paying off with all kinds of good little critters. i just got done building a sump today out of a 10 gallon tank for my 30gal reef tank. i was going to use bioballs until i read all the feedback about people removing theres and using their rock instead. so now i'm going to use a 4" sand bed with 10lbs of rock in the sump and run a 13 watt PC at night while my tank is in night mode. i was told my PH should not move with this type of set-up. and that way i have a refugium as well. anybody used this methood and how has it worked out?

Not a flatworm nor Stomatella. From what I can make out in the pic it appears to be a bi-valve of some type. Possibly a yound mussel that will soon stop wandering and attach itself somewhere.

I'd agree with Guy- best pic is here- http://communities.msn.com/vulkumsreefpics/shoebox.msnw?action=ShowPhoto&PhotoID=1

Quite distinctive shape, and the split between the two halves of the shell can be seen here- http://communities.msn.com/vulkumsreefpics/shoebox.msnw?action=ShowPhoto&PhotoID=4

I have one that came from Marine Ecosystems just like it. The "hairs" are incidental, and most likely are tube worms or forams that are living on or in the shell.

It's definitely not a flat worm. I'm kinda with Guy on this one-stomatella snail (a good thing).
