I was looking up this book
and came across this quote in the first review:
"These reason Marine Angelfish and Butterflies are left out of this book and also the subsequent volumes, is that this is a German book written in English and the government of Germany banned the importation of all Angelfish and Buterflyfish. There is no point talking about how great Angelfish are if you cannot get them wheer you live."
I would just like to know why if this is true and I'm having trouble finding info on Google.
