I've had a Pistol Shrimp in my FOWLR for over 2 years now. I have/had a Pink Tail Trigger, Blue Chin Trigger, Niger Trigger, Humuhumu Trigger, Blue Ring Angel, Bursa Trigger (RIP), and Clown Trigger (RIP). The Pistol is still there. If it's a crab you have...maybe. But then, how will you know when they've dealt with it?
