The role that trace and minor elements play with shrimp, other crustaceans and riverine fishes is related to neurological and metabolic processes (in which these elements play critical roles), as well as overall coloration (trace and minor elements are often at the core of pigments known to enhance coloration). Dosing a trace and minor supplement with every water change performed is an effective method of delivering these substances for maximum benefit. Many freshwater shrimps are native to tropical and subtropical waters of Asia, Oceania and Africa. In general, most will thrive in water conditions similar to mose freshwater fish species. Parameters within the following ranges is generally acceptable: pH 6.5 - 7.5; dGH 4 - 6; dKH 3 - 4; however, obtaining the water parameters in which your shrimp were bred and maintaining them in these conditions is the best practice to follow. Certainly, research the web to obtain more specific parameters recommended for the exact species you are keeping. A number of popular ornamental fish species, such as Cardinal Tetras and Neon Tetras, Rasboras, White Clouds, and Glassfish are often found in the same water conditions in which shrimp thrive; hence, ShrimpCode may also be used in aquaria housing these fishes with equal success, as well as catfish species such as pygmy Corydoras, and Kuhli loaches.
