Wow such aggression. Worse than 2 tangs in a 20 gal... It is disappointing to give away a frag only to have someone kill it. That being said, we've all lost plenty of frags so yeah. It's also a good idea to give a peice away that isn't doing well in your reef. Maybe it well do better else where, so props. It's abviosly losing tissue, and whoever wants it can always dip and qt to try and avoid future problems...
