Your biggest mistake

[Jory]

when i was 14 i was moving a tank and we decided to make 2 trips, my mom later said we would have to go back for the actual fish, which i had left in a bucket. we went back the next day and roughly 13 fish were dead.
lesson learned always bring fish, a heater, and an air pump first...

I once fried 20lbs of live rock setting up my first marine tank when I somehow FORGOT to add any salt at all.


Thats a very expensive mistake...

Did they have ich when you bought them, or did they get it once in your tank? Two totally different things, and blames. Too many people think their fish COME with ich, even though not present on the fish. Mine's probably getting distracted while doing water changes. You realize you've made a mistake when you hear water rushing to the floor.

I guess it was partly my own fault for not looking closely at the store. When I got home and they were still in the bag, I noticed small white spots on them. I didn't have the heart to take them back, I wanted to rescue them and I did. They are all healthy now.
