Glass Tanks for Betta Fish

All-glass aquariums are still the most popular. Made of plate glass and sealed with nontoxic silicone that allows for expansion when the tank is filled with water, glass tanks resist scratching and provide a good viewing area. One disadvantage of glass is the difficulty of drilling holes for filter parts—something that is easily accomplished with acrylic
tanks.

Glass tanks are also much heavier than acrylic tanks and can be difficult to move, especially when the tank is large. The glass must be increasingly thicker as the tank size gets larger to support the increased water pressure. Glass tanks can break, too, leaving you with a huge mess to clean up. Fortunately, such disasters are rare.
