Used to ride home from lfs with fish in a bag on handlebars. Used to take almost an hour. Luckily the weather was mild and most survived.
A couple that I'm somewhat acquainted with wanted to come see my planted freshwater tanks. While they were over, they fell in love with my saltwater tank. One month later they've set up a tank and were adding massive amounts of fish and corals to a tank that hadn't even completed its cycle. I warned them to slow down and tried to explain that nothing good happens fast in saltwater. I see them a month later and a bunch of stuff in their tank has been dying (surprise, surprise) and they're like "what's happening, I don't understand?" They claim their parameters are perfect... well most of your fish would not be dying if that was the case! Their tank is not even two months old and they've already added multiple anemones. It was a huge mistake to let these people come see my tanks. They already "know everything" so they aren't interested in learning how to do things the right way. They are already thinking of giving it up because of a cyano outbreak. For the animals sake, I sure hope they do.
