I want to sell mine as soon as I catch the bugger.
I think he's responsible for wiping out my feather dusters and christmas tree worms.
In addition, my bristleworm population also decreased dramatically since I got the Peppermint shrimp. I've read on RC about other people having a decrease in bristleworms as well after getting Peppermints. I actually saw him eating my Cocoworm.
I only have a couple of Christmas tree worms left and they close up during the day and come out only during the night.
