So I noticed bleaching on the base of one of my sps, and I saw what looked like a bunch off eggs and I saw one white nudibrach. I havent added any sps in my tank since RAP, and the last thing I added to my tank was a rbta 2 months ago. I only have 3 other sps frags and I already took it out.

My heart sunk when I saw the title. The base does look like it's been eaten away. Those little things look like more baby nudis, rather than eggs.

If you're not super attached to the coral it's probably easiest to just toss them and let the nudis die out for a few months before adding more SPS. If you want to keep them hit up Schnitzelreef for how to beat them. It took him months of dipping often to get rid of them but he did.

I already tossed the one they were on. But all I have is 3 other sps frags and a couple of montis. I had the sps on a frag rack, do you think thry could spread to the lr where my montis are?

That sucks I just had the same prob and just did dips on affected coral and scrubbed them with a toothbrush and got rid of them!


135 sps dominated tank.

Unless that wrasse will eat the eggs then it'll help control but won't solve the problem.

Where are Wickedfish and Schnitzelreef on this? How'd you guys beat 'em?

I can't exactly describe what's on your frag. Telltale signs of AEFW are usually bite marks on coral and then egg bundles near base.

Most pictures that I have seen show AEFW bite marks not really the destruction in your photo. Acropora eating flat Worms are really hard to see on coral---again I have never even seen good pictures of them on coral because they tend to take up coral color and become almost perfectly camouflaged. The rolled up one in your bottom of container looks like it has some type of colored fringes at its edges and that is not what I would expect either. But I am no expert by any means. Tektite on r2r is pretty darn knowledgable.

In terms of prevention: 1) inspect carefully looking for bite marks and egg bundles. 2). Cut off plug from frag. 3.). Dip in Bayer. 4). Quarantine if possible Oh, and did I say dip in Bayer

Thanks for your input but im very certain they are nudibranchs, if you zoom in on the first picture you can see an adult. Will bayer kill them and the eggs?

I've never heard of an acropora eating nudibranch...I was under the impression a nudibranch was either a montipora or zoa/paly pest. Those eggs are most definitely AEFW. I'll be following along to see how this progresses. Good luck

I just reread this and I need to apologize. I meant to say "most definitely NOT AEFW." I can't seem to edit my post. All the AEFW eggs I've seen are greenish brown in color, and they usually start out around the base of the acro. I've never seen them bright white like those in your picture. Anyway, good luck figuring out what they are and getting rid of them.
