And i'd much rather re-seam or replace the tank than come home to 55 some odd gallons of warm saltwater covering the carpet of my APARTMENT (that's the worrisome part) and a tank full of flopping, gasping and or dead creatures.
My first tank was a 35 converted from freshwater. My brother came messing around my room and opened my sliding closet door, which slid down it's track made contact with a square glass lid on a 5 gal bucket I was mixing water in, which slid into the corner and chipped a big enough piece out of the edge for water to squirt out. That was likely the most stressfull experience i've been through.
Fortunately though I had some damn hardy fish I was able to sell back to a local fish store. (Niger Trigger, 2 Sergeant Major Damsels, Snowflake Moray Eel, (here's the funny part - a couple sea cucumbers, a bunch of brittle stars, hermit crabs, starfish and urchins that I had smuggled across the border from a trip to Mexico.....shhhhhhhhh nobody needs to know about that one.) to my amazement all those inverts slowly disappeared.) That was before I was a little more familiar with saltwater food chains and tank size to inhabitant ratios.
