Maybe the proper course would be to go to someone really high up in the chain, and somehow convice/entice them to take an interest in the better management of thier livestock. Make them aware of everyone's concerns and offer to help or provide some guidance in some way. Maybe offer to write some standards and protocols for care. Get them to attend a meeting or something where they actually see what a healthy tank really looks like.

Then as the AHEM rolls down....

Of course another action could be:
Dear District/Regional Manager, the news is here with thier cameras doing a story on the pitiful shape of our livestock and that we even turned down local hobbyists offering to help. What do I tell them??
