These are swimming independently, not sessile. Did not come from my tank but it looks pretty close to red tide, nope they are not eggs folks... Best picture I could get....
Hard to tell..you can't get a close up? looks like baby brine shrimp that just hatched. They are red/orange in color and swim in jerking motions..you may know that already..thats what it looks like to me.
oopsy...this photo was taken with a microscope at about 100x magnification.
They are not eggs, not brine shrimp and do have some internal movement as well as a 'swimming' ability. Several of us are stumped by this......
