On at least two ocassions i have found a swordtail on the floor, and it must have been atleast 3 or 4 minutes out the water. This would have been from moving buckets of fish about and then 3 or 4 minutes later finding a fish on the floor (usually kitchen) from the positon of where i had moved the bucket from (i.e. thats why i am pretty sure fish out of water for 3-4 mins)
Unless the fish got crushed, i would be shocked if it died having just been out the water for anything less than 1 minute (adult fish).
When my Malawi tank smashed all over the floor, i had to rescue about 30-40 fish, and i was decorating so my living room was a complete mess. It took me at least 10 minutes to find all the fish. The only fish that died was one that i trod on accidently and two that i didnt find until the next morning.
In fact out of about 30-40 fish, i am pretty sure i was only missing 3. All the others are alive and well to this day.
If you had told me a 300 litre tank could smash with close to 40 fish in the middle of a cluttered room and 3-4 months later only 3 fish missing / dead, i would not believe you
The water went all over my flat, no puddles anywhere, once the fish left the tank, that was it, they were not in water!!!
