Daphnia are People Too.
Ok all, I have a quandry for you. Ever since I was little, I have been a fan of collecting rocks/minerals/fossils ect. I have some very cool pieces that I am thinking about adding to my tanks, but the internet has given me mixed ideas about this. In specific, I am looking at amethyst, jade, and malachite. I am not concerned about the jade at all, but the other 2 have yielded mixed opinions from my research. All pieces have been collected by me and washed properly, so I am not concerned about contaminants. They also don't react to the fizz test, but I read that the iron in the amethyst (which gives it color) may not be good and that some of these rocks can have a surplus of Manganese. Ideas? Experience?
