In a big aquarium, waste produced by fish is watered down throughout a massive volume of water. In a tiny bowl or a two-gallon tank, that same quantity of waste can quickly surge ammonia levels, showing fatal to occupants. Moreover, many fish species need ample swimming area to thrive, grow, and exhibit natural habits. Constraining them in undersized environments results in stress, stunted growth, and reduced life expectancies.

Classifying Fish Tank Gallon Sizes
