this happens every second of every day. as we speak someone just bought a 6 inch jag for their brand new 20 gallon that has no heater. sad. you cant go nuts about it but the best thing you could do is keep people informed. try working at petland making attempts to sway people away from making these kind of choices, at times it feels like talking to a 3 year old child about why people die....... same way you may see a 95 pound women who knows nothing about dog training buy a pitbull or rottweiler puppy. you kind of scratch your head and wonder "hows that going to turn out?" meanwhile you know the answer. you try to explain things to people without offending them hoping they get the point...these things happen on a massive scale tho. wants-knowledge+luck ...lol at times its a ticking time bomb. I just feel bad for the animals
