So today I took out a seed pod from my axies tank, underneath it as I dug it up I noticed that the sand was black (my sand is the color of brown sugar) and this worried me so I sucked up and put it in a cup. Does anyone know what it is? It does not go all over the tank it was specifically under where the seed pod was. I didn't throw it away in case it's beneficial some how but it is out of my tank now. Thanks in advance. (Hope it's ok to post this here)
