I agree with what you are saying.  I know that this aquarium ban is also based upon bad/no science and is being driven by mis-guided emotion.  I wish everyone in support of this ban would watch the film "Chasing Coral".  The film is a muiti-year study conducted by real scientists and includes Hawaii.  The real problem is temperature change causing a mass bleaching of coral on a global scale which directly impact all fish populations.  In the mean time we waste resources on a silly ban that will have no impact while the coral continues to die.
