Well my common pleco jumped out of the tank once before and was out of water for at least 10 minutes but a good rule to follow is "never keep a fish out of water for more than 60 seconds."
I got a better rule of thumb. Don't take any fish out of water unless your transfering them in different water
What you should do is get a clear container add some tank water to it and add the pleco to it and take your pic. It might work for ya.
It's ok i got some pics of him and put them up http/www.fishforums.net/index.php?showtopic=120289
Bit of a shame he is nocturnal really, although after lights out last night he was haveing a right feast on my logs!
