A type of Freshwater Fish
It depends on the type of fish and plants that are in the aquarium. For most tetras, danios and swordplants, a pH of 6 is preferred. For guppies, platies, swordtails, hornworts and cichlids, a pH of 8 is ideal.
Mouth brooding cichlids and some saltwater fish to my knew
It all depends on the type of fish you have, but 72-82 degrees is pretty safe. I'd keep it around 76-78.

Freshwater is a type of water with a low level of salt.
The soil types in freshwater biomes are generally categorized as mineral soils, organic soils, and sand-based soils. Mineral soils are composed of clay, silt, and sand particles with various levels of organic matter. Organic soils are rich in decomposed plant and animal matter, while sand-based soils have larger particles and lower fertility levels. The specific soil type in a freshwater biome can vary based on factors such as water flow, nutrient availability, and vegetation cover.
