Thanks everyone for your suggestions! I started moving the fish from the leaking pond at work with out any problems so far. Ive been using totes. They seem to be in good shape but I decided to use 2 35 gallon tanks to hold them for now as the pond they come from looks like a mud pit and I want to check for disease. So I have one question the last fish I need to move its a koi that looks like a 5lb. bag maybe 2 lol of sugar with the longest fins i have ever seen! He's about a foot and a half if not more and I'm afaid to injure him. Should I pump the water out instead of netting him, I dont want to rip any fins and how big of a tote to transport a little room or more for him to prevent injury? I love this message board, but I think my husband realizes he's lost me to the fish!! :D lol Again thanks for the help it's great to find a good place to talk fish.

Moving larger fish can be a challenge especially if they put up a fight. If the other fish are already out, and you can, pumping down the pond so the big fish is in less water certainly makes it easier to get him. The koi professionals use koi socks which are long nets to put the big fish into. Most regular nets are going to be too small so you might try a soft towel to pick him up. Expect him to be hard to handle and expect to get wet and dirty. Once you have him, you can put him into a container that's large enough for transport. Be sure to net it or cover it (with air holes) for the move. The container should be big enough to hold him but with little room to move which may just result in more thrashing. If the drive is short, you shouldn't have to worry about things like ammonia. If it's a longer drive, more work needs to be done. If fins are damaged in the catching and moving by accident, be sure to add some pond salt and MelaFix to his/her new home to aid with healing.

Good luck! I hope it goes ok.
