Aquarium Advice Activist
When on vacation to central California, my young daughter found a small rock washed upon the shore. It is 1"x1"x2", so very small and would fit perfectly in my 10 gallon fw planted tank. The rock is tan colored but I don't know what type. What are some of the concerns, if any and what precautions should I take? Any advice would be highly appreciate!
