I noticed today after cleaning the glass near the sand bed that there are hundreds, possibly thousands of super tiny white specs on the lower portion of my glass. It appeared to me that some of them are moving on the glass. Obviously curious what they are, hoping it’s not a bad thing. I have about a dozen trochus snails, 10 zombie snails, several different fish species, and two dozen hermit crabs. Could it be eggs? Systems is 110g about 4-5 months old.
