"The laws in place have zero to do with people who like to keep native fish that grow large and want to have a proper environment for them. "
WRONG
You have to understand that the laws put into place are to protect our native wildlife. If you want to remove a species from the wild to grow in an aquarium you HAVE to follow the laws, or serve jail time and get fined. Follow the rules or there is no place in you for native fish keeping, other wise its called poaching.
On a side note, you might want to use that 500 gallon you plan to build, for your fish in your other aquarium instead of a northern pike -->http://www.monsterfishkeepers.com/forums/showthread.php?448440-STUPID-STUPID-CLOUDY-WATER!
I will be getting rid of the fish I currently have in my tank in one years time as I always do. There are circumstances when I can't make myself get rid of a fish so in those cases I get a bigger tank. i feel its good to switch it up. The Pike would be a fish of my fathers and mine and i would be splitting the costs and buying a 500 gallon not building. I already said I'll be sure to get a permit idk what the big deal is?
