Not to my knowledge. (I'm not as diligent about testing as I should be.) The roughest part was finding my melanarus wrasse when breaking down the old tank. He shot into the sand, so I had to be careful to find him as I was removing the sand and actually ended up catching him by hand as I was scooping.
The second day after the transfer, everyone was out and about and eating. The bubble coral seemed the most affected, but he also fell into the carpet anemone early in the process, so it's difficult to say if it was the transfer or the stinging action that ticked him off.
