I find these little circle things every morning after the light switched on, what are they? They seem to be getting more now. Some one glass and some on rocks.

This is one I focus on a live rock

There are 3 on the glass

This is the whole tank view, I have 3 corals,two fish,2 blue hermits, 1 turbo, 1 astra, 2 nassaixxx snail.

help!

White circle thing with tentacles?? They are some sort of jellyfish I think. If it is a new tank they will die off after a while. Hard to see for sure though. Also nice rock work. I like the way it is set up.

Thanks.

Yes, my tank has only been up 1.5 months. Still not sure what they are called I asked many people, lol. Hope it's not harmful.

Do an image search for Cladonema and/or Staurocladia and see if anything looks right.
