Hello fellow reefers,

A couple of weeks ago, I purchased a really beautiful blue-purple acro and I was so happy about it.

However, two days ago, I found a whitish acro crab in the branches. My friends said to me before that there were two different acro crabs, one contributeed to coral health and the other was just a pest badly eating corals. The one I got was this one.

It looked different from what I normally see. So I kicked this one out. But this wasn't the end of the story. At the back of the acro, I found some sort of egg-like thing embedded in the skeleton of the acro. It was covered with sand and I couldn't identify what that jelly-like thing was. It was so creepy that I took it out immediately and throw it away.

After I put it away, there was a relatively deep ditch. It looked like something dug it.

Please note that the base of this acro was white in the LFS. The LFS said it was a part of the bigger acro before being cut into pieces. Actually, the base started turning brown after it came to my tank. The issue here is not the white base, but the egg-like thing and the ditch.

Before I put this acro in my tank, I dipped it in Revive, but I didn't notice this at that time. Probably, there wasn't this thing at that time I believe.

Does anyone know what's that egg-like thing? Eggs of bad acro crab? One of the experienced reefers I know had once told me that the bad acro crab is relatively ok until it starts reproduction, but once it started reproduction, it could cause a huge damage. Is this something he had told me about?

If they weren't eggs. What is this? Can I simply leave this acro in my tank? Is there anything I should do? Thank you for your help!

Well the store is right, it was definitely cut there... when it was cut from the ocean. :D It appears to be a wild piece, also why it had the crab. And yea that was a bad crab. Almost looks like a gorilla crab. However, crabs don’t lay eggs to my knowledge. They keep them on their body under their belly when they create eggs.

Do you have a close up of said eggs? If it was eggs it wasn’t crab eggs.

Thank you for your input, Ledreef. So it means worse than crab eggs, right? Do you know how to treat? I think I removed all of them, but If a piece of the eggs was left in the tank, it could cause a disaster, right?

If those were newly hatched eggs, AEFW is already in my tank, not brought from the LFS. So I think I need to do some kind of treatment. Does anyone have suggestions?

Did the eggs look like this?

Actually, at the time I found it, it was covered with white sand. So I am not sure. It looked more like jelly. Also, it was completely in the ditch, not on the surface of the coral.

In the ditch could still be aefw. However aefw egg doesn’t look like jelly. It’s pretty distinct. It might have been a sponge that was dying or decaying. I wouldn’t do anything right now. I didn’t see any bite marks in your pics.

Can AEFW dig deep in the skeleton? Or does it eat only the surface tissue of coral?

Dips will not kill any eggs.

It just looks like a wild cut to me. If you want, scrub it with a toothbrush, or a slightly stiffer brush... egg mutilation works.

Hi jda,

No, it doesn't look like a wild cut. Look at this picture that I took now.

I used a tooth pick to remove everything. So nothing is there now. It was very easily removed. And the thing was kind of like jelly as far as I remember. I should have observed it closely.

As you can see, there is one big hole at the left side of the ditch. And it's deep. So it doesn't look like a natural thing, right?

Trust us, it’s a wild cut acro colony. :)
Ah, is it? This is a true relief! You know, finding something unknown made me feel like in a serious trouble. Besides, I've read so many worm disasters here and there. Thank you, BoomCorals! By the way, you have a collection of great-looking acros! I wish I were in the US to buy one of yours! ;)
