More than a decade ago, i only caredabout fish, didn't bother with the physical aspect of tanks. Got this old 2nd hand tank 8x3x2 for almost free (it was already kept dry for a year or so), used it for marine couple years, then changed to freshwater. Foolishly decided to DIY my own version of bakki shower on top of the tank, with no additional support. As anyone would guess, bracing broke, filter box and glass covers and bracing all crashed into the tank. Comm tank of 9 x mature red aros. happened during the night. i woke to find 8 x dead red aros on the floor. quit the hobby for years. to this date i can still picture the scene extremely vividly lol.
