Anemone eggs.

Are you kidding?
I thought it was some kind of pest-critter!

Small Heavens · 09/30/2017, 08:54 AM

I seriously thought the anemone would die.

Small Heavens · 09/30/2017, 09:18 AM

Oh, please, somebody say that it is true and it's eggs and not pests!

What kind of anemone is it? M. doereensis?
Eggs does not move that fast. The only host anemones that reproduce with internal fertilization are E quadricolor, H malu and S gigantea. I have seen fertilized eggs in the mother in all three of these species. They do move actively but only slowly almost like go with the flow of fluid. However I know that they self initiated movement because I see several move pass each other in opposite direction in the mother tentacles.

The animal that move in the video posted by the OP cannot be anything other than a crustacean somehow living inside the anemone. This the first I have ever seen. Is the anemone healthy as far as you can determine? If he is well, just continue to take care of him like normal. If he is sick I would recommend treat him with Bayer insecticide. Bayer is very effective against crustaceans but safe with coral even at resonablely high dose.

Yes it a Macrodactyla Doreensis. I gave it a cup for its foot as you've recommend and it settled smoothly. It's in a specimen tank by itself and the rockwork I prepared for it seems to make a nest that it has approved of (so far). It is reacting sticky, accepting food, although it is slightly bleached but not too badly. It's foot is way-way too pale, more or less same colour as the disk and and skirts.

I noticed first one, then two of these small tiny dots.
It took some time before I realised that they were inside the tissue and not outside it, but they move everywhere, including up into the tentacles and are clearly just hanging out in there.
They seem like a sand spec, with a tiny tail or something.

The video is of the biggest one I have seen, and appears to have a tail almost like a crustacean?

I could see three today at the same time, so it has at least three of them, but none of those I saw today was the bigger one from the video. Perhaps it has left the anemone.

Thank you so much for the recommendation of the pesticide, I was very worried that I would have to see the anemone be eaten alive by some pest.

It's amazing that so much can be going on inside our pet anemones, thank you soooo much for helping me clarify this Minh, I really appreciate it and clear answers in the hobby can still be really hard to come by.

Am I the only one who sees a copepod with two egg sacs? I also see what appears to be color spots on the anemone itself and I do not think they are eggs.

I totally agree, it could be the two eggsacks of a copepod giving the shape of it.

And the spots on the tentacles is just colouring.
