So my dad called me frantic this morning and it seems his new BTA had a little fight with his gyre. Needless to say the nem is decimated with pieces of him everywhere. I personally have not had this happen to me but I have heard horror stories. I told him to remove every piece of the nem possible and start making some water to do a change. Are there any other steps to take to prevent any damage or death to the other corals or fish?? any help would be greatly appreciated
