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 dont know what else to call them almost like jellyfish. too small for pic w/o macro lens which I dont have yet. they crawl on glass slowly. not pods.their round with two pointy legs but all one piece. any clues?
Dave.They are not a problem in small quantities. When(if) they get out of control and over populate your tank, they will become a problem. Treat for them now.
I've read of tanks getting invested by them. I'm not to sure how they reproduce but some people say that a skimmer will take care of them on the early stages, and the safest way to get rid of them will be to get a natural predator like: six line wrasse, mandarin or a leopard wrasse.
