Trust me you don't want restrictions on fish. It will only lead to more and more restrictions, higher prices and less revenue for the LFS. And when you restrict something you make a black market. You also open up "straw purchases". The key is education. Yes it would be a beautiful world if things like that didn't happen. The truth is that most of those fish are cheap and lots of people don't care. They don't look at fish like they would a dog or cat. IMO you would open a whole new world for PETA to constantly push for more strict laws. As far as I know the only non-endangered (CITIES) freshwater species banned ,here in the states, on a Federal level are snakeheads. I don't want to see anymore unless they are a threat. I am also sure someone can still obtain a snakehead illegally in the states.
How can you verify a future tank size?
Special Order? I like to see the fish in person and observe it for at least five minutes. How do you know it is the "right" one? I also try not to buy a fish if it has not been at the shop for at least a week.
What does "More information required at LFS" mean? If it is that they need to know your tank size? That wouldn't fly, but I like the idea. People already lie to the LFS about their tank sizes to get the fish they want. I have seen people on here rant about how the PetCo/PetSmart employee had the audacity to ask how large their tank was.
Leaving it as it is would be the best option IMO. People that want to learn come to places like this. Even people who "want to learn" refuse to learn here. A very well known person on here for their picture threads and sexing threads is very extreme example. This was not meant as a low blow, only an example.
I am giving this as my whole hearted honest opinion. I may get flamed, but I think we are loosing way to many privileges and rights in this country as it is. These are my two cents, plus some. I am anti fish control!
Edit- PETA against fish from their website
