Help weird critter in new live rock

[angdtr]

I am a newbie we put in live rock a week ago and this strange lime green creature with alot of legs scurried very quickly across the tank. We have not seen it since. I am getting ready to put in my cleaning crew and I am worried about what this critter is and if he will harm them.
Thanks,
Ang

do you have pictures??

 

[angdtr]

not now I only saw it once. I am trying to get him out with food to take a pic. It is no bigger than and inch very long and skinny and extremely fast. If I can catch a pic I will post it.
Thanks,
Ang

I hope you don't have a mantis

Does it look like a worm? Do a search for bristle worms. There are some harmful worms but more good ones than bad ones.

I am thinking mantis.... They are a green color, very fast, and have many legs... Common in new live rock...

I think you would know if it is a shrimp or not.

That is true, however if you look at pictures of the famed mantis they do not look like shrimp in the traditional way, and if the one that the poster has is small, less than an inch, I would even be hard pressed to see exactly what it is as it "scurries very quickly" back into the rock...JMO I am going purely off of description, I know of very few other creatures with many legs that go very fast and are neon green...

Does it look like this?

He does not look that pretty when I did see it. Still trying to get it out to take a pic of him. Got him out once but moved so fast I could not get the pic. I hope he is not a mantis. I also have a hitchiker snail and it has not bothered it. Still cannot get over how fast it moves. LOL

Do you know if it's a fish? I'm very curious.... :joy:

Do not think he is. Never seen it swim. Stays on the bottom. Only seen him twice he is hard to get out. Just curries very quickly. Tiny fast little bugger. I think I am just going to try to catch it and take it out if I can since I cannot figure out what it is. I have been looking all over trying to find something that looks like it.
