Slug, Sea Hare or worm??

icyunvme · 03/20/2013, 08:33 PM

I found this creature in my tank this morning. Tonight I found a few more. It appears to be dark green in color but somewhat see through. It may have some sort of partial shell on the back? Ive been googling all day and can find anything that looks like it. Lots of similar things, but not that. Can someone please help me identify it before I lose my mind?!?

Wow, weird little dude! You might try the ID forum, Sushigirl and LeslieH hang out there and they seem to know their stuff with hitchhikers.

I think it's either a dark form of Haminoea antillarum or H. elegans, both Atlantic species. If I'm wrong maybe one of the experts will correct me.

Definitely a Cephalasipdean as Don said. There are other species that are dark, best to do an image search on Google. http://www.google.com/search?q=site:...+Cephalaspidea

Thanks everyone! Ive been driving myself nuts trying to figure it out. So should I leave them in there? Some site say they eat detrius and some say algae, but nothing says they are bad. So far I have found 3 of them.

If in doubt let it live I always say
