IDs, fish, acro problem and acro crab

First of all these silver fish with yellow tails, they constantly school and eat like pigs. I love them... just don't know what they are.





Next, I have been having a problem with this specific Acro for a little while. I'm thinking this crab I snatched out of it is the culprit. I took a picture of the acro with the crab in it then the crab in my sink.

 

I don't recognize the fish enough to put a name to them, but I can say that's NOT a friendly "acro" crab. That needs to be a new perminant sump critter.

 

So we agree that the tissue issues on that colony are probably a result of his presence? (all my others look great)

 

+1 on the crab. Typically a hairy crab is up to no good.

I think the fish are silver moony, a brackish fish.

 

Oh, how I love 3reef!! Silver moony seems dead on, and the crab is evicted! Hopefully the colony will heal up now!

Thanks ya'll!
