I have a tank with daphnia happily living and breeding in it. Can I reasonably assume that water is safe for shrimp, too?
Yes, I know that pH, hardness, and temperature would affect what kind of shrimp I can get; and I know about ammonia, nitrite, nitrate, cycling, the dangers of shrimp-munching fish, and the value of a mature tank with biofilm--I have done a fair bit of research.
But I'm worried about the things I wouldn't otherwise think to test for (like the copper in the tapwater at a previous house: it killed fish overnight, even though the water was "perfect" according to the tests the store had. Took a while to figure that one out.)
So it it reasonable to think that "daphnia safe" also means "shrimp safe"?
