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 the blenny scratching itself against a rock? if not, i wouldn't worry about it. it seems like he got into a fight with another fish. i don't think it's the anemone's fault. it looks like something picked at it.
Unfortunately there's no way to know w/o having someone with experience examine him. Again I suggest you pass a good pic to Bob Fenner, as he has veterinarians in his group.
