Folks, if you've recently upgraded or renewed your annual club membership but it's still not active, please reach out to the BOD or a moderator. The PayPal system has a slight bug which it doesn't allow it to activate the account on it's own.
Is that a yellow octospawn? i have the same piece and absolutely one of my favorite corals!
as for the micro bubbles, maybe try moving your neros down a little bit. it may be sucking up water from up top?
