My CBS has never bothered my fish. He does a threatening gesture if the damsel comes too close, but stops short of attacking. He doesn't bother the mandarin at all because he is well aware that it is poisonous.
My guess is that if your CBS kills anything in your tank it can be one or a combination of two reasons.
- The fish or invert was sick or injured to begin with.
You are not feeding your CBS enough food and/or frequently enough.
My CBS tries to start a fight when I put my hand into the tank, but he never actually pinches. I think a lot of the agression is show. I love this shrimp and it is my opinion that if you could have multiple shrimp, or just a CBS....I would go with just the CBS.
ps- I don't think your cbs is capable of causing any serious injury to an urchin.
The behavior of my CBS is exactly the same when I put my hand into the tank!! He's also very curious about new additions to the tank, but I've never seen him harm anything. I have, however, seen him give my fish a threatening gesture, but at the moment, they're all too fast for him to catch (and I think the fish make a game of it...let's antagonize the ol' guy :hilarious). I don't think he'd know what to do with them if he did catch them...hmmmm. Like I said, Scampi is here to stay...my son-in-law thinks he's a great addition to the tank, and frankly, so do I.
