Tang Police or Tang Nazis?

[mr.wilson]

I don't know how the whole tang police thing started. I have never seen any evidence of tangs being stressed in a reef tank, due to spacial limitations. The other claim that I don't understand is that tangs need high water flow.

Marine fish do best in smaller tanks (1-20 gallons) with respect to wholesale and retail facilities. Retailers that use large holding tanks (30-150 gallons) cause more fish injuries, fish-to-fish disease transmission, aggression, and trauma as they are netted.

The reef structure design is more important than the actual tank size. I agree, wrasse can cover a lot more territory in a short time tan any other fish. They have well developed swim bladders so they can dart up and down as well.
