$100 says they eventually resort to poisoning the lake and end up only killing the few that were there, while taking out all the naturally existing species, killing every native creature that comes in contact with the water, and probably contaminating the water table.
people throwing there unwanted pets in the lake give us all a black eye, burry them in the back yard, throw them in the dumpster, eat them for breakfast, but please dont release them!
I can't believe they would even think of poisoning the lake. That would be more idiotic of them to do then the people who let the fish go in the first place, let alone do more damage.
