What's the dumbest thing you've done?

[Pier Pressure]

We have only been in the fishkeeping hobby for two years and it is so hard to choose what was the absolute dumbest thing. There have been so many!

I think maybe my initial mistake was my worst. I bought a 150 gallon aquarium as a "starter kit" because I had heard the water stayed more stable. We lost many fish before we finally discovered we did not have enough filtration action to properly keep the tank circulated.

Well, go big or go home I always say. So we are now running a Reena XP3 together with a Fluval X5 on that tank.

Saltwater screw ups? Don't get me started!
