How can you remove a BTA from live rock?

[Jyman]

I read some where, I think it was on canreef here that you can put a zip-tie around down by the foot. Just make sure that the zip-tie is not really tight and he should release in a couple of hours. All you want to do is bug him enough with it and he will move.

I have also read that you can use a powerhead and point it right at him and that will get him to move because they don't really like high current.

Do you have any pictures of the BTA's and how they are on the rock?
