Sick Skunk Fish - I think

Last week I got a new skunk fish, a diamond goby and some snails. A couple of corals. I am very new to this. My water was fine, I did a change of water then slowly introduced the guys to the tank. Everything was going great. Yesterday I noticed that the shrimp was in the front corner of the tank with it's tail against the glass. He hasn't moved from that stop all night or this morning. I thought he was trapped some how, but that is not the case. He moves a bit but doesn't leave that corner and keeps his tail up and his head down. He has not died yet. Can anyone help me with this?

 

the shrimp was against the tank??

Im gonna assume that you eman the fish. Well if you do, it sounds like its dying, you say you water is fine, but.... what do you consider fine?
How long has the tank been running, and what are your parameters?

Chances if this is a new tank, its not yet mature enough to sustain fish.

 

Hello, not sure about the post. Is the skunk fish ailing? As far as the shrimp, sounds like a defensive posture. Is there enough live rock for cover?

 

Are we talking about a sick fish or ticked off shrimp?
