Light refraction
Glass has a higher index of refraction than water, thus causing your
views to be slightly distorted. Position of your fishes seems
inaccurate and the colors seems off. Whereas acrylic has an index of
refraction which is close to water's, which means you can view your
fishes with the least distortion. This difference is very apparent if
you do a side-by-side comparison.
Acrylic wins!
Breaking
Unlikely to ever happen, and i hope it never do for both you and I. As
when glass breaks due to sharp impacts, it will shatter! This can cause
some serious injuries and damage. Acrylic is much stronger, is much
harder to break, and will not shatter the way glass do.
Acrylic wins!
Color
Acrylic will turn yellow over time. This is due to a chemical reaction with light and is unavoidable.
Glass wins!
Shape
Fish-keeping is not only about having beautiful fishes. The fish tank
itself has to look good and fit well together with your furnitures.
Acrylic allows manufacturers to bend and mold them into appealing
shapes. Examples are curved tank corners and curved side walls. As for
glass, it is brittle and difficult to bend. And when bent, it makes
objects on the other side of the glass look much bigger or smaller.
Acrylic wins!
Conclusion
I hope this article has helped you, in understanding more about their
differences, and in selecting a fish tank that truly suits your needs!
