I have a number of these small white things attached to the glass. They are slightly larger than the copepods I have for size reference. seem to be clustered but randomly placed. I have a number of CUC snails. Been battling dinos so haven’t cleaned the glass. It’s like a white pinpoint attachment and the fan like projection moves with the flow. They are to small to clearly make out. I was hoping a snail egg, maybe some filter feeder. I haven’t seen adult aptasia so hopefully not babies from unknown source . 2nd pic is magnified
