mods can be done with money also and that takes no talent! by not allowing mods you have to use your talent of being able to work with what you have. plus it keeps it cheaper for the people who are on fixed budgets.
I agree that the contest should be fair to all, however I do believe that people voted without much thought as to what could be kept in a tank with inadequate lighting. I wonder if they voted again if they would change their vote. I will go along with whatever is decided. If we can't grow anything but mushrooms then so be it. Maybe we should change the contest name to Mushroom Pico Contest?
