My tank is roughly 3-4 months old... I purchased 20 lbs of "aragonite" sand from lfs
, then added 20 lbs ls
from liverocks.com during the first couple of weeks, totalling 2-5" of sand (water currents change depth in some areas due to phs). Everything seems to be great in the tank - now populated with a couple of clownfish, peppermint shrimp, some snails.
I've noticed something looking through the glass at the sand - a ton of small cavities or air pockets in the sand. Is this created by creatues, or buildup of gases in the sand? Is this normal? Or are these perhaps translucent creatures? I have found worms in the sands, creating their usual narrow paths up, and I have what I think are pods
now on the glass...really the tank is teaming with life. I'm just not sure about these little pockets of "air" in the sand.
