You should be careful taking things from the wild and putting them in your aquarium. They can carry diseases and parasites. The bleach will probably take care of that, but you may want to soak the rocks in clean water for a few days, then let them dry in the sun. If it fizzes, don't use the rocks in your aquarium.
