When we lived in Myakka our tank was on Bruce Hardwood Laminate. It was not the Pergo pressed but was the 3 layers of real wood laminated together. The FLoor was glued down to the slab. I had no problems with that floor. Alot of water and abuse. I would not do it with the european laminates though that are pressed board. We have several rooms of Pergo, but it does not like water.
When we sold our house the buyer was real worried about the floor under the tank, and made us move teh tank prior to contract. Needless to say it looked better under the tank then from the normal wear around the tank.
You could always make a tiled pad kinda foyer like with the wood wrapping around it. Might not look to bad...
