101-150 Gallon Aquariums

This size range is perfect for hobbyists ready to take the next step in their saltwater journey. With more room for rockwork, coral growth, and a wider variety of fish, 101 to 150 gallon aquariums offer a strong foundation for serious reef or fish-only systems.
 

These tanks give you the space to run more advanced equipment, maintain stable parameters, and create a display that really stands out. Whether you’re planning a centerpiece for your home or building out a dedicated fish room, this collection has plenty of solid options to work with.
