I was transfering a 10" calcarifer to a bigger tank and ran into problems. I neted the fish fine and put him into a cooler with some of the tank water, as soon as I took it out and released into bucket he's upside down! I had this problem before when moving 16 4"ers to a 120g. Its been 5 hours and still upside down. He was doing great but its like his equilibrium was thrown of or something. I even tried holding him in front of a powerhead for an hour with no avail. I hope he pulls through the nite.
