Do inverts (shrimp in particular) really need so much work done in water parameters? RCS seem like the guppy of the shrimp world, but reading about the others (bamboo, bee, snowball etc.) makes it seem like they need as much care as discus. I keep seeing strict PH, GH and KH levels dependant on species. Is this really necessary or one of those things that people make it seem more difficult than it is?
