I wonder why people keep saying that in articles about the nitrates.BottomDweller said:They don't reduce nitrates but they will eat some of the uneaten food which would have created ammonia.
I would probably have 1 ghost shrimp per 2 gallons in a tank with a normal stocking density of fish. In a heavily planted tank with no other animals I think you could have 1 per gallon.
There is no minimum number.
I think what is meant by that is shrimp take care of leftovers an some poop before it turns to ammonia . less ammonia = less nitrate .CarrieFisher said:
