Hi,
Here's a fun newbie question.
We have a 3 gallon tank with a happy beta, 3 neon tetras, and a little snail.
We recently visited a gem mine where my son did some panning and found some pretty rocks-- including a nice sized chunk of iron pyrite.
It's pretty and sparkly, and he wants to put it in with the fish.
So, can iron pyrite harm the fish?
