What types of rocks can kill your fish? The reason why I ask is because someone gave me a lot of rocks that he used for an aquarium. In the past, I found some rocks that were put in my aquarium toxic; the water parameters were normal.
Types of rocks that can kill your fish

only those that will raise the pH of the water.
so anything with calcium/magnesium carbonates (basically limestone) in them
otherwise, rocks are inert and won't affect your fish.
if you lost fish after adding rocks, and it wasn't something else that killed them, they probably raised the pH up too high.

good article on rocks in aquariums: just pulled off the web so I can't comment on its validity though:
