I've been looking around the creek behind my house for a long time looking for rocks to stick in my aquariums. I found two that I really liked.
I poured vinegar over them multiple times and they didn't fizz, so I take that as a good sign. But I just want some opinions on if they'd be safe for aquariums.
And if they are, should I boil them? I've heard some rocks could explode if boiled.
Thanks for the help.
