ok usually all of them where from inside the ocean water all at least still wet on the beach. BUT, as i said i think i made a big mistake with one of them.
because i found a nice broken coral formation but at this day i had too much to carry (on that beach we have to walk thru a really humid tropical forrest because its a hidden beach) and i left it on the beach outside of the water. one week later i saw it again and took it home. in the car i realized that it started to stink when it got in touch with the water in the cube so at home i tryed to "clean" it as good i could from plants and everything on it but it still looked kind of dirty.
anyways i used it for the aquarium and the fishes ate from it and loved to hide in it. after the first fished started to die i thought it was from that
so i took it out with everything else except 3 rocks i had in the from the beginning. its really clean in there.
