Never out of a filter....That was close. If the leak had been worse and you not there to deal with it...
I have on the other hand gotten distracted when changing water, and syphoned all the water out of the tank. This happened in my fry tank with about 100 molly babies! It was so low that the kids were sucking water from out between the rocke!
I refilled the tank, and had at least 99 still there, live and kicking. I was lucky, and felt just horrid, but it seems to happen fairly often, just never that much.
My usual water change, I syphon water out of all the big tanks, then go start the generator to refill (water pump needs the big generator). The syphon job takes over an hour and I don't want to run the big generator that long......any way, I was doing this the other day, and one of my 55 got down to only about 10 inches of water in it before I noticed what was going on....It all turned out ok. The fish didn't seem any worse for the wear.
You didn't know you were going to do a water change when you got home, did you.
