In my experience, DIVOs are worthless until proven otherwise and rarely do they complete that task. Also, they change around rather quickly. Just tell your husband to get his fish asap so he looks no different than anyone else. The DIVOs can be good but they are not really necessary in my experience. Your husband will be fine but I think from what you said about him, he might be served by growing some teeth. Him being best friends with the cones is not going to help him back aft.
Good luck,
Andy
