Whats this

[chris55]

Think this is a better forum for this thread, I found this crawling on my back wall its about 1/4 inch long and has a slug like bottom on it, the bubble that you see in the picture were like bristles before i touched it. I got a rock from another member a couple of days ago and Ive been seing critters left and right. Anybody know what this is, and what is it diet and what are the threats to my tank?

It's a nudibranch but I couldn't tell you what kind. Most only eat very specific foods and some can be quite damaging to a tank. Keep an eye on your coral because some of these can eat them right up. Hopefully someone else will pipe in on the species.
