I know we come here to help one another but after a while it becomes like babysitting. When you start to see several folks state the same thing over, and over and over it, its get obsessive. The rules and regulations are at the top of this forum. If they fail to read that or anywhere else, thats there problem. They get in trouble in local DNR, then again thats there problem. Its not you getting in trouble, you're not getting fined, etc. You can tell that person 100 times its illegal, etc. but that doesnt mean its going to stop them.
Anyways, most of the time, first time offenders get a slap on the wrist, not a HUGE fine or whatever. Its a case by case basis. Some guy in KY I think had a snakehead in his tank, thats a fish not even native to the US and all he recevied was a $250 fine and fish confiscated, thats not a HUGE fine by any means. If you are a repeat offender, have possibly an endangered species in your tank, threated species, or any other special item then you MIGHT get a nice size fine.
If we just worry about ourselves, instead of what others are doing, this would be a much better place. I dont see folks telling everyone in the buy sell trade area which goes on all day long, that you need to check your local laws to see if that fish in banned in your state, so it shouldnt be done here either. (Yes I know there is a person once in a blue moon that does that but nothing like what goes on in here)
