Not sure I would have been so quick with the death sentence. Looks like a cool shrimp. IMO
most shrimp are harmless, beneficial additions to a reef. Esp. rare ones like this.
Mantis shrimp are an exception and aren't really shrimp anyway.
Maybe a QT
tank would be a good place to put questionable creatures pending thier dispostion. Might be able to make some $$ from fellow members looking for odd creatures. I think I would have paid money for that guy.
