Poor thing, I'm a part time receptionist myself and was once faced with the very same issue--oddly enough, it made me fall in love with the species. It is a terrible pity that they're used in this way, because they are such intelligent and vibrant creatures when they are housed and treated properly. If you don't mind me asking, where, generally, are you located? We might be able to direct you to some local resources for rehoming the poor man.
Would you be willing to help take care of him if we gave you the advice to do so? In that case, if you could list everything you have to work with, including the size and type of container he's in now, whether it's heated or not, and water additives you have, and anything else you can think of, it would help us give you the best advice possible for dealing with your situation.
