Well last night I was spot feeding some of my brains and sun coral when I decided I wanted to break up this zoo rock I have. This zoo rock has like 5 different types on it, blue rim green mouth, green rim orange mouth, pink rim orange mouth, green & orange with white blotches, etc... Anyway, I pulled the rock out and brock the crap out of it and out flew this little shrimp with one big claw and one little claw. The shrimp is about 1" long and brown. I had been hearing snapping sounds and was worried I had a mantis shrimp, I guess this little guy is good, no? I read that they make buddies with gobies or something to that effect. I have a yellow watchman, will they help each other out or whats the deal. I put the shrimp back in the tank, hope this was not a mistake. Thanks for reading.
