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.
I set up a 14Biocube about eight months ago, and in the past couple weeks, I've noticed a bunch of little half-red, half-blue ribbed worms crawling in and out of the rocks, and one in particular is almost 4 inches long now. Any idea what they are, and are they harmful to the tank?
Thanks in...
