Great post, it's crazy what people will buy to put in their small tank's, without doing any research what so ever. Example : "Just got a RTC for my 20g tall, how long till I need to upgrade?" "Is it true he won't out grow the size of the tank?"
how can one do that when they're at the store? I don't see pet shops offering internet kiosks
hell I dont see people researching what breed of dog they're buying when they're cute cuddly wuddly puppies so its as bad all around same goes for cute little teeny fish they think is the most adorable littlest critter in the world.
I think you need a part about "fw" puffers since many require brackish to be happy and many just toss them in with whatever tank setup they have. not good all around
