possible pests on coral

Michaelriccs · Oct 11, 2016

So looking at my tank tonight I saw these white curled worm looking things on my one Zoa frag with what is most likely a baby Aiptashia (spelling might be wrong). The first photo attached is of the zoa frag after I dipped it. The white "worm" did not come off. The next photo is of my torch are the red things on the base anything to be worried about. The third photo is of my letpastrea. Are the blueish spots on it something to worry about. Thanks, I would like to prevent a catastrophe

the zoa have nudibrach eggs on it. You have to pick them off. MAKE SURE YOU WEAR GLASSES, better yet do it under water. The toxin will blind you for life if it squirts in your eyes. The red spots are on mine too and I think are normal in the coral. And I dont know about third.

If you have eggs on your zoa you can bet you have a ton of nudi's in your tank. I discovered the same thing and have dipped mine a 4th time tonight in the last month. As soon as they stop opening regular or dont seem "happy" its dip time again. Keep your eye on it. WEAR GLASSES!!!

Well thanks for that I was scraping them with my finger. I'm still able to see so I guess I didn't get any in my eyes lol

Where do you see nudi eggs?

I see spirorbid worms on the zoas, completely harmless filter feeders. What you are seeing is actually the "shell", since you've dipped it more than likely the worms themselves have died.

Don't know whether or not anyone cares but I contacted world wide coral to ask them about the blue spots on the letpastrea. apparently they are hermit crabs. Pretty cool stuff
