If I were to build an inclosed storage shelf so I can house 5-6 tanks in a garage would I need to use special wood on the inside of it? I'm not sure if all the water evaporation would cause any harm, mildew or something like that.

Any wood will do if painted with a sealing paint. Kilz is available at home depot or Ace hardware and is a top choice for moister barrier and mildew control.
If you want to be safer then pressure treated lumber is the next step but it adds to the cost quite a bit. Metal stands painted with a waterproofing paint or even good old rustolem would work as well.
