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.
While I was cleaning my tank I found this little guy. Is he a pest? I am thinking nudibranch, but someone told me that if it’s not white it may be eating my corals.
I’m adding photos from what it looked like inside and outside the tank.
