While nitrate is much less toxic than ammonia, [20] levels over 30 ppm of nitrate can inhibit growth, impair the immune system and cause stress in some aquatic species. [21] Nitrate toxicity remains a subject of debate. [22]

All guppies and mollies are hardy fish that tolerate lower oxygen levels and temperatures than most aquarium fish, give birth to live young, and readily breed in home tanks.

In fishkeeping, suitable species of aquarium fish, plants and other organisms vary with the size, water chemistry and temperature of the aquarium. Freshwater-specific lists:
In contrast, freshwater invertebrates are more tolerant (~90+mg/l), and adult freshwater fish can tolerate very high levels (800mg+/l). [51] Nitrate levels also contribute to eutrophication , a process in which large algal blooms reduce oxygen levels in bodies of water and lead to death in oxygen-consuming creatures due to anoxia.
[1] Such fish are good starter fish can be used for 'cycling' an aquarium (i.e. reducing ammonia and nitrites to effectively zero.) [2] [more detail needed] Examples of hardy freshwater fish include Poecilids such as the guppy, [1] molly, swordtail and platy, most species of betta, zebra danios, and some tetras. Generally, fish are hardy only ...
