I think that would work. Treat the center as the background Sort of.
The only problem is that in a 55, it is so narrow you will effectively be using a 6" wide tankk from each side.
Depending on how the tank is mounted and orientation of the equipment, it may be easier to concentrate the wood and larger plantings toward one side and have a wraparound beach or lawn on the other, more like a peninsula than an island.
.02 worth what you paid for it. Enjoy.
