WOULD YOU BUY A 150 GAL TANK THAT IS 72X18X28 0R 1 THAT IS 60X24X25? ..Both calculate out to be approx 155 US gal. I'm thinking the shorter wider tanks give me more surface area.
The difference in the surface area of these two tanks is not so great that I would use it as my determining factor. I think what would be more important is what you plan on keeping in the tank. If you are going to keep active swimmers, then the longer tank would be better in my opinion. If you plan on keeping cichlids or other territorial fish, the wider tank would probably be better as the extra width seems to allow the fish to pass each other without feeling as crowded, at least in my experience.
