my big silver has been on the floor many times during moving it always sacred the crap out of me and left a nice poop stain on my white carpet in the old house
Most expensive/rare was my Endlicheri endlicheri (12 inches)...The net had a smale hole and fish made it bigger and voila, he was on the floor. Pain in the arse to pick it off the floor. Didn't make it.
arowanas mostly.. a flowerhorn , a temensis ... but the most nerve racking one was when a large retic got her stinger caught badly in a net. She was thrashing all around and cutting the net off was a real adventure.
