As stated above, I appreciate your concern for proper care for tangs Naesco. As much as people resent the "tang police" I agree that informing hobbyists about appropriate/ideal husbandry is certainly productive even when it's not what they want to hear. Additionally, I don't believe that my "experience" precludes me from being scolded if necessary. And that's why I noted that I would remove the tang immediately if it demonstrated any signs of declining health.
