I have had this in my aquarium for about 3 years it came on a piece of live rock that I aquired. It is about an inch across and the foot that it hold on with is about an inch and a half across. I believe it to be a carnivore due to the fact that it takes hole silversides about twice a week. Here are a few photos that I took of it. It is tanish red in color with white stripes

Hi,

The images are pretty blurry and small for any definitive identification. It looks to be a sea cucumber, but such animals would not eat silver sides. Can you post a better image?
