Personally I feel that keeping animals in general is bad unless they are to be bred and released. If you think about how much we pull out of the wild purely to show case in a glass box its mind blowing. And each animal vertebrate or not that we remove damages the ecosystem just a little morr. Yes we could provide a healthier life for these animals but that is not their purpose. They need to grow, reproduce, and die, and that is how it has to be for life to continue. That being said, I am without a doubt a hypocrit because I know these things and yet continue to collect and keep them and do nothing about it. So like Thales said, its not just the ignorant to blame, we are all at fault.
