So... I have an aquarium with my collection of ten discus that I expect to in time begin to pair off (and I’ll decide which to keep to minimize the collection).. I see Jack Watley in Miami use them in all of their breeding tanks so I want to put a couple in so they have a smooth surface when the time is right. At that point I would have to divide the setup... but what I’m asking is, how do I know if these are sage? They will have no effect on my ph or other water parameters?
