The other colours are just as hardy as cherries, like cockroaches. I would recommend the salty shrimp Sulawesi minerals over a shrimp substrate because they're designed for soft water shrimp, cherries can live in a wide range of parameters but will do will do better in some conditions than others. I'm not saying that, but those substrates are designed for shrimp that hail from soft water, usually Caridina cantonensis, not Neocaridina heteropoda, they come from harder water than the crystals and you can buffer them with coral chips or the Salty shrimp minerals. The thing that the shrimp substrates would do that those can't is bind heavy metals often present in tap water as they have a lot if carbon compounds that bind them up, IAL and soil will do the same thing.
