John,
I'm happy to see this thread finally! Good job on the move. Looks like it wall went very smooth. I know the feeling of waiting for fish to recover from MS222 oh too well.
Love the pictures and a well written summary of the event. Congrats!
To everyone else,
Sedating obligate air breathers (especially arapaima) is an art that not many professional aquarists will tackle. The words and pictures here can't begin to describe how much prep and care went in to such a task. This is huge for a hobbiest to accomplish.
