Please help me ID this thing

[causeidm]

First of all, sorry for not posting a picture, I am still trying to figure out why all the pictures come our blurry. This morning just before the lights in my tank turned on I found what looks like a small (1/8th-1/4 of an inch), fat, catepillar? at fist I thought maybe I had some kind of crustacean and a fish ate in and it was just the abdomen, but I rulled that out when the thing started moving and I noticed little things that looks like really really small apastasia coming from its sides. The top is blue, belly is milkish, I quickly caught it before it got in the LR and I have it in a jar. I have not yet rulled out it being part of a dead crustacean, except that it was in my main tank, not my refugium, so there are no hermits or snails or shrimp...that I know of...in it. Any help would be appreciated

Can't help you with the ID, but if your camera has auto focus on it, turn it off. The auto focus is most likely hitting the glass and causing the blur of everything behind the glass.

sounds like bristleworm to me.

Ditto on the bristleworm.

 

[frankl15207]

Based on the color description, it doesn't sound like a common bristle worm.

could be some sort of cucumber. in the past i have found little ones that came as hitchikers.
maybe this will help.. <a href="http://habitatnews.nus.edu.sg/news/chekjawa/ria/text/cucumbers.htm" target="_blank">Cucumbers</a>

You guys have been a great help. I have been looking at every picture of any kind of hitchhicker that I can find and the closest thing to it has been cucumbers. I considered the nudibranch, but it has like leg things poking out of it and is not at all smooth like most of the nudibranches I have seen. Plus, I can't even tell if it has a head, but I did notice that it has a dark brown spot on each of its ends. Other than that, I'm still clueless. I have tried taking pictures again, but my camera is a kodak digital camera and I think that it might have auto-focus and that I may not be able to turn it off, or at least I can't find the option to do so.
Thank you all for your help!

Ahhh - my brand of digital
Go to your Menu
Advanced Exposure Mode
Programmed AE
Advanced Focus Mode
Select Manual Focus and Infinity
Since it is a Kodak, you confirmed my previous suspicion that it is focusing on the glass.

Hey frankl15207, Thanks for your help with the digital camera, much appreciated...but my model is a DX3600 and I can't find the options you gave me in it. all I van find are brightness, date/time, video out, image storage, format, cloes up, quality, and a few more that don't matter. any sugestions?

 

[frankl15207]

You're right. I have a high level Kodak and the model 3500. The 3500 has the same settings as your 3600. There is not an option to disable auto-focus. Sorry about that.
