    I have been noticing some tiny things, about 3 - 4 mm wide, fluorescing on the bottom of my tank, near some green ricordea, and thought maybe they were baby ricordea. They were lumpy looking like a ricordea. The color was the same, and I thought, well if they siphon out maybe they are something else because those ricordea stick to everything.

    I was siphoning out detritus today and looked in the bucket, and lo and behold there were about 20 of them on the bottom of my bucket, but each one is now only about 1 mm wide. Evidently some that I had been seeing were entire groups of them in the same spot. They appear to be too small to be euphilia tips, but the color matches. One of the things in the pic sort of resembles a very tiny hammer coral tip, but it was very tiny.

    I don't have any fish that like to nibble on corals (at least that I've ever observed, or any types that are notorious for coral munching). They are brighter in person than what the pictures show.

    I thought they might be:
    a) Ricordea juvenile polyps that had not yet attached to anything?
    b) bits and pieces of ricordea that a crab or something has been decapitating?
    c) bits and pieces of euphilia that a crab or something has been decapitating?
    d) tiny euphilia buds that detached to find a new home?
    e) something else?

    Has anyone else seen this? Should I gather these up and do something in particular with them? Are they just dying pieces of tentacles? For the time being they are in the bucket awaiting a verdict.

    Thanks!

    Did you try poking them to see if they move?

    I just prodded a few around and they don't seem very reactive.

    I say leave them alone and see if they grow. They are already in your tank and if they bother your other corals and such remove them. If they grow well and are cool sell them.

    OK I am tossing some of 'em back in the main tank, and the rest in my 3.6 gal pico to see if they grow. Hopefully they don't stick to detritus I have so much flow it will be tough for them to find a good place to land :confused:

    Maybe I'll shut off my pumps for an hour or two when I move 'em over. Will post later here what happens to them... stay tuned for the exciting conclusion. Hope you all can live with all the suspense. LOL

    So, related development: i too have a mystery green dot! I got some frags from you a few weeks ago, but nothing this color. I sucked it up it off the sand, put it on a large plug, and covered with a shot glass. We'll see what happens!

    My guess is D. I’ve had this happen in the past.

    I DO have a hammer coral, and the color is right. Is it possible it will form a new coral, or is it just a partial that will fade away?

    Can you post a pic of it? Is it stony or soft?

    Did they live? Any advice?

    One looks almost shaped like a flatworm with my eyes. They can take on the color of what they are eating. Not a ricordia polyp, nor a baby ric or other shroom. If it is a tip from a hammer or torch, it will not live. If you can get a better picture under daylight, that can be more helpful.

    Someone knocked over the shot glass overnight and it blew away, will keep an eye out for it

    OK, here is the update as of today... they were bright green for about a week, and all of them died, despite location.

    Interesting. I was almost leaning if they were ejected pocillopora or stylophora polyps. Bummer they didn't live! That would have been a sweet experiment.

    The shot glass would not allow enough flow to keep them alive, even if the glass hadnt been knocked over.

    No, but was hoping it would give it time to anchor down if it was something that could do so
