Is it safe to hang framed photos in a room with a large aquarium?

Hello.

I volunteer at a local park and plan(ned?) to display framed 11 x 14 and 16 x 20 prints in both its welcome office and small nature center. The former is a large (kinda welcome office-sized (maybe 30 x 30ish feet)) room with a single 100+ gallon aquarium. The latter is small nature center-sized (20 x 50' maybe?) and has a small pond and several large and small aquariums.

Up to now I've donated smaller framed images but these pieces will belong to me but will hang indefinitely until I need them for art/craft shows, temporary display elsewhere, etc.

I'd hang as far as possible from any water but is this unwise regardless? Would paper backing help? If it is an issue, can anyone speak to how long it might take to cause damage so that maybe I could offer them temporarily? If I'm willing to risk long-term damage to the (replaceable) prints, would I need to be concerned about the (Michael's/AC Moore type wood (some composite)) frames as well?

Appreciate any comments.

You say its an office as well? I cannot imagine a very humid environment going down well with the workers. Which may mean that its atmosphere it is not over damp? The room with the pond might be a different matter

I dont think the fish will steal the pics. so you are safe!!!!

Kidding asside. If the building is climate controlled (a/c and heat), humidity will not be a problem with that small of a tank. The only time it gets to be a problem would be city/county/state aquarium sized tanks.
