ID Please

Postby gsrsk8er on Mon Dec 31, 2012 3:24 pm

I have noticed a couple of things growing that I'm not exactly sure what they are. One is growing on a rock next to some green daisy polyps and the other is growing on a rock that had some zoa's on it. I'm not too worried about them, just curious.

Any help would be appreciated.

Looks like mini feather dusters but they are growing in bunches

the green thing is an algae. looks like codium to me. the top photo isnt close up enough for positive id but i would guess either colonial tube worms or the nonmotile stage of a jellyfish.

The second photo is Neomaris Annulata. I'm 100% sure cuz I got it in my tank. I didn't know what it was for the longest time and then I stumbled on a website that had a picture of it... Read up on it. Some say it's bad and some say it's not. From what I read, it can take over a tank in a hurry. I've had two stalks on separate rocks for over a year now. They haven't multiplied so I haven't been concerned... but some of the stuff I'm reading online (and pics) have me watching this stuff.

The colony of things do not retract into the "tubes". The green thing has grown fairly rapidly, I first noticed it about a month ago as a green spot. Should I remove it??

I get the neon green growths in mine also. I have been pulling them out.

I kinda like your other things that look like feather duster.

Destroy the hydroids! I had those things a long time ago. They can spread really fast. They will sting the crap out of your hands and arms if you brush up against them and you will then have little itchy burning bumps all over. When I used to crush them, strangely, what was left my sailfin tang loved to eat up.
