Saltwater Aquarium/STRANGE GROWTH IN SALTWATER AQUARIUM
Expert: marcus - 1/28/2014
Question THERE IS A STRANGE GROWTH IN OUR SALTWATER AQUARIUM. IT IS STUCK ON THE SIDES OF THE TANK AND ALSO ON ROCKS AND CORAL. IT IS TUBULAR WITH HAIR LIKE TENTACLES. WHEN FOOD IS PUT IN THE TANK THE TENTACLES REACH FOR THE FOOD. THEY SEEM TO BE MULTIPLYING.
Answer Hello Lorraine,
it seems to me from your description that this hitchhiker is most likely simply a colony of tiny feather dusters. with tube like structures and tiny hairy like tentacles that sway in the water this is almost definitely what you are seeing. if so, then there is no need to worry. they are harmless and actually are a pretty cool little hitchhiker in my opinion :)
i have about 15 years of experience in the reefing hobby but have been keeping aquariums for about 20, i am up to date on all the latest equipment such as led lighting, dosers, the new tanks available such as the red sea max and i can help you with many creatures that most other people have never even kept before such as sehorses, cephs, and sharks and rays.
15 years in the reefing hobby and it has come to my attention this site needs some more informed experts.
