Yep! I remember early on when Finding Nemo had just come out, my local Petco's fish person was telling me it was a nightmare with people buying clowns and then putting them in fish bowls with fresh tap water and then demanding refunds when their fish died within minutes/hours. So "Do you have a saltwater tank?" is the first question I remember from my LFS/Petco prior to a purchase. Prior to that, it was just trial by fire for the most part.Oh for sure. That was my my first thought too. 20 years ago, there wasn't so much info at our fingertips. I went into stores, I bought stuff, no one asked me any questions and just assumed I knew what I was doing.......we all know how that ends .
