I guess the point I was trying to make with this poll has been proven. Boxfish are not dangerouse just people who buy them with out researching. Responsible owners who know how to take care of them never have an issue with tank wipe out. I am guessing that most people who say their tank was wiped had one of two things happen. 1. Their tank had crappy water parameters and was tetering on the brink of destruction and the boxfish is a convienant excuse. 2. They had the boxfish in a tank that was to small, or too aggressive.
