My tank is experiencing a weird thing right now on the front of the tank there seems to be incredibly small snowflake like organisms on the glass there seems to be about 100 all in a pack..spaced out enough so I could most likely count them...I've never seen anything like this...It doesn't appear to be an algae but im not to sure what they are... Um also my tank base is crushed coral and they're are quite a few live organisms in rock at the base of where all this is happening and i was wondering could they maybe be eggs stuck to the glass?? plz help
