Had that happen with a 40 gallon I had on our living room mantel. About 5 min after we woke up I heard a pop sound. Did not quite know what it was until I heard the filter water getting louder and louder. Come to find out that the seal just blew outward about the size of a large pin. What a mess. It's amazing the tank waited until we were all awake and in the living room for it to happen. maybe there really are the "FISH GODS" huh? I am glad it turned out ok for you too.
I probably would die in a situation like this...
Not prepared in least bit. I would be probably having the water drain into a Rubbermaid tank. And put my fish in the tank. My banded leporinus would probably fly out of the tank. Hes the hardest to catch. I just see it as a huge disaster.....
