Hi all!

Any idea what this little critter is? Good or bad?

Thanks in advance

As mentioned on the other thread (for anyone interested, you can click my username at the top of the quote below and it will take you to my post in the other thread):

You're going to need some higher contrast pics of the slug - any chance you could get it in a container of tank water and take some pics of it from the top and the side (showing the full body length with both) under white light, preferably against a black background?
