Tiny Spiders on the Glass?

[MWelch]

Right-but they don't move the same way a brittle star moves. They look like transparent spiders that are only about the size of a peppercorn or smaller. They are very strange looking.

I betcha that is what they are for sure.

They are now gone off of the glass now so I am thinking somebody or something likes to snack on them. Or maybe they moved into the rocks.

I am just glad they are not some kind of infestation!
