Do Damsels dig?

[Oakie]

I have a blue devil damsel.....I also have a large excavated portion of live sand out from under some of my live rock. I can't see anything else in there but the blue devil damsel.....do they dig?

Yes damsels do dig. My dad has a blue damsel and thats all it does is constantly dig.

Have had him for a couple of years....only the past month or so I've noticed the digging............aaaargh - he's impossible to catch and now he's making my rock work potentially unstable.....aargh!!!!
