Hahah I love the bit about the feeble goldfish and his larger fish friend that helped him out. 1 example out of a 1000 where another fish helped out, rather than just killed or straight out ate the weaker fish.
Also its hilarious how they state, if you have fish, this is what you can do to make life more bearable for them. And then in their list of tips they describe how to cycle a new tank! Those evil fish-store supporting bastards!!!! I love how they call fish stores "Dealers" too, makes them sound like your neighbourhood drug dealer. "I'd like an ounce of smack, and 2 gourami's!"
The whole bit about disrupting their communcation via our pumps and filters makes no sense either. Unless you have your air pump vibrating and shaking away right in side the water I don't see how its vibrations even get into the tank. And your filter, hell, people use HOB or Canisters which again do not transmit mass waves of sound and vibration into the water, All your filter does is create current, which they would have in their natural environment anyway. The only noise equivalent might be your airstone churning up bubbles, but then, this is a condition they would run into in the wild as well with fast moving water or air bubbles in the water. If their communication was so disrupted you'd think that for example schooling fish would have trouble schooling properly, but that's obviously not the case. Hogwash.
Obviously by purchasing fish you have to realize you probably indirectly are supporting some illegal, or at the very least unethical fish capture practices. But people will always buy pet fish, just like people will always keep dogs and cats. So boycotting by not buying fish isn't an effective way to combat those problems. Plus, are you seriously going to tell me that there is not a single member of PETA that does not own a fish, or a dog. By owning a dog and purchasing it from a pet store...
...your supporting puppy farms!
I don't buy either that fish suffer horrible excruciating lifes in well kept aquariums either. Mine routinely chase and play with each other and interact with the other fish in the tank, not the sign of an animal doomed to a insufferable trying existence.
