Some of the most popular Fish in this group include Betta Fish, Platies, Swordtails, and Neon Tetras.

Fish that fall into the middle group, which do well in pH levels between 6-8, include Guppies and Mollies. These Fish can tolerate a wider range of pH levels than Fish in the first group.

Fish in the third group, those that require hard water (a pH level of 7.5-10), cannot be kept in soft water aquariums, as they would die from the low pH levels.

There are many popular fish choices for soft water aquariums, but it is essential to research before choosing which one will be best for you.
