I have one of my neighbor's peppermint shrimp in my tank due to aptaisia I "aquired" along with some macro algae. Normally peppermint shrimp are benign, but I've watched the little booger pick polyps off of a frag of Orange Delight Zoas! I'm going to try a homemade shrimp trap with a water bottle (cut the top off and put in back in upside down to create "one way" style entrance) and frozen brine. Any ideas as to how else I might catch the little scoundrel?

Really, every shrimp I have ever had would eat right out of my hands. I think the bottle trap would be the way to go.

It worked like a charm. Set it up last night and the shrimp was waiting for me this morning.
I think this one is being problematic because it was wild caught on the Texas Gulf Coast. We had a large influx of them in our reefclub during the summer. I think this is the same shrimp that attacked and killed my friend/neighbor's feather duster. His other 3 shrimp are much more easy going.

I had a cleaner shrimp that used to kill my snails. I had to take him back to the LFS.
