Whats frustrating is that people don't research animals before hand. Responsible Business Practice is one thing, but the fault most certainly doesen't fall on the business alone. There are a million threads about this, but unless you want the government to intervene in which species hobbyists can and can not keep in a home aquarium, it is ultimately up to the consumer to research an animal before they purchase it and responsibly home it. And then you can say, "well the local fish store said it would only get this big..." I say it is irresponsible to listen to the local fish stores suggestions on size, because they make $8.00 an hour and the majority know nothing any more complex than 1 inch per gallon rule, (not all, I have come across some VERY knowledgeable employees). Point is, Ichthyologists will not be frequently working as aquarium shop employees, and unless you want to pay 15 dollars per neon tetra for excelent advice, do your own research, don't impulse buy, and don't expect to get flawless information from your local fish store employees.
