I grow it here and clip it. I take a bunch with me when I go to service tanks and just put it in the veggie clip. The tangs,(hippo and yellow) normally fairly shy, will sometimes come charging out and tear into it before I can get my hand out of the tank. I've never seen it hang there for more than about 2 minutes and they always manage to knock the clip off the glass.
Life is not measured by the number of breaths we take, but by the moments that take our breath away.
