I have a Bristle Worm Assassin.

Was looking through my tank last night and seen one of my NJ hermit crabs rip a bristle worm out of the hole it was in and eat it. Just wanted to share. :)

Sorry about the picture qualitly but the camera phone was the closest thing to me.

Pretty cool! I spent many of nights scouting out this suckers because everyone was telling me they were fireworms. My weapons of choice were a red flashlight, tweezers and persistence :)

Even after getting nine HUGE ones, over 8" extended, I just saw one climbing around the other night.. they never seemed to cause anything harm..

Those hermits will eat anything they can get their claws on, fish included. I've seen then in shells the size of baseballs all the time when I dive the back bays.

Your probably thinking of Pagurus arcuatus. They're the ones that get huge and have a flat claw. These guys have been in my tank for over a year and have never taken a fish. There in with a small YWG, 2 dart fish, and a Lawnmower Blenny, also with handfuls of blue and red leg hermits, astrea snails, nassarius snail, orange linkia starfish, and 2 feather dusters. They also have never harmed a coral or climbed a rock(never leave the sandbed(EVER)). As far as these guys go the largest on is in a turbo snail shell with lots of growing room(cant see it when hiding in shell). ;)
 
Do they sift the SB looking for food? and did youo you catch this one right from the beach or did you go to an LFS?

Yes, but its just barely the top layer of sand. When the get scared or go to shed they actually completely cover themselves in sand. And the only ones I got from the LFS are the redlegs and bluelegs. These ones were actually caught next to the closed fishing pier in Ocean City on the bay side.
 
Sandy Hook, NJ - bucket o hermits....took my girls maybe 30~60 minutes (this was last summer) to grab all of these (plus the eastern coast whelks).

I have a couple of these in my nano, and they are viscous little crabs.. when food goes in they go crazy fighting with eachother. one which has since went back to his beach home even was pulling others out of shells he decided he wanted to move into. I had mine in a small 2.5g QT for a couple of months with fresh shells. I selected the least mean ones and sent the rest back. Many have "snail fur" on their shells which looks cool, but I was worried about.. They have been in my main tank for about 3 months now without issues to corals or fish. I did have 2 cleaners go missing though.

I notice mine stay mostly on the sand bed, and never bother corals except when I am trying to feed my scoly then one of them always tries to grab the foor which i remedy by grabbing him the the tweezers and holding him in the air until the food is gone..

If I was to do it again, I think I would just stick with purely store bought hermits.. while these are entertaining to watch more then any other hermit, they aren't as useful (at least mine) as many other types. I have really started to forgo the standard cuc packs and get specialized crabs / inverts to target things I need help with.

The snails however (they look like whelk's you have pictured) are awesome at sand sifting and I would get more of them without hesitation.

When we where in Island Beach State Park this weekend we saw people seining on the bay side, and they had pulled up 5-6 tropical species. I saw a couple of different angel fish, a tang a basslet, and what I think was some sort of wrasse. it was pretty cool.. I'd love to get a net and see what I could get out of these one day since they most likely will die off in the winter might as well try to save them (and my wallet) once I get the 90 up.
 
I have a seining net.. I've been meaning to go this summer but haven't yet.

When I was younger I had a seahorse tank and I kept the smaller species of local hermits and never had any issues. I never kept them with coral.
 
I still haven't seen a seahorse. :( Seen everything else for the most part (pipefish, gobies, snails, crabs, ect.). I've been out a couple of times, lost a shoe, but still no horseys.

They're hard to come by unless its late September or early October for some reason. Unfortunately it's right around the time where the temperatures are just becoming too cold for a nice day of seining.
