51 - 100 Gallons

In many cases, saltwater aquariums in the 50 to 100 gallon range are the best of both worlds. Large enough that you have more abundant fish options vs a smaller aquarium, but small enough that tank maintenance doesn't become overwhelming. Most tanks in this size range are between 3 feet and 4 feet long, so they can still make for an impressive centerpiece in your living space or office.
