Sea Slug

You sure that's not a cuke?

Here's another pic. Still look like a cuke?

Well I'm no expert but Wei's often has cukes that look very similar, except they are pink. I could be way off though, have you checked www.seaslugforum.net? I cannot tell how big it is, it does appear from the second photo that it is more flat than turd shaped, which I think would mean it is a slug.

Yeah I was going to say, it sort of looks like one of those yellow ones you can get at King Ed sometimes, except without the little feeding appendages that stick out of one end.

Definitely try the seaslug forum.

Christy :)

Ok. you guys are right, its a cucumber. Hm, I'm trying to find out if it poses a toxic threat if it is harassed or dies. :) If I can't determine that, I'll probably get rid of it rather than take a chance.

You know what they say about cukes, the less colourful the less toxic. Makes sense of course, although you wouldn't want to take that as a guarantee. Personally I'd keep that one. Everyone warned me about the nudibranchs I had in my tank that were very colourful, and several of them have died without any negative effect on the rest of the tank.
