what would it be( No pics sorry)
 

Well I have a bottle trap setup trying to catch what i believe is a little mantis
But my cleaner shrimp seem to thinkthe bottle is a cozy place too and have to be helped out twice already. Tonight i notice this little 1/2 inch spiny "slug" looking thing in the bottle and now trying to go back in. Is this what it could be it moves real slow and covered with little pointy thorns sorry no pics yet.

My guess is.....Stomatella Snail!

They come in gray or black usually.

some sort of nudibranch maybe..?? :confused:

Do you have Zoos?

There is a type of Nudi that has a spiny like back. There are several spines and the nudi can be dark black to grey/white looking. They eat zoos and lay eggs on the zoos. Not sure if they harm other corals. Here are some pics of the bad Nudi. There are 3 pics.

I do have zoo's but it's not eating them
I really have to pick up a digital cam again
It's not flat looking like a nudi It's more like a blackish color overstuffed worm with little spines& it narrows to the mouth area :confused:
