Green Pods?

There are some green pods in my reef tank. They look like they are the same as other pods in the tank only green. Are they a different species of pods or are they just eating something different? I searched a bit, but didn't find much.

Here is a pic of one of the green pods:

 

Almost looks like a bristle worm???

 

no way thats a bristle; maybe its a shrimp? I've seen neon green shrimp but I think there freshwater, so im honestly not sure here

 

Looks like an isopod

 

could be

 

I think there are different colored 'pods. I had some that were blue and red after I added some new cheato to the tank. Those colors were under a flashlight at night.

 

oh well i did not know that; my pods are usually just white

 

I think you will normally see white ones, tan ones and gray ones.

 

yeah thats what i have virtually all the time

 

I have green ones. They're the ones that have been eating the green algae in the refugium LOL. The reddish ones are the ones I see on the cyano, the gray ones are the ones I see rolling up balls of detritus and carrying it off, and the white ones are usually hanging in my chaeto.
