Thread: What ARE these?

  1. #1

    Default What ARE these?

    0 Not allowed!
    They look like budding snails, but they are rock hard when I scrape them off and don't seem to have a snail inside?
    I find them occasionally, in differing sizes. This one is the biggest yet. The calendar square it is on (for scale) is 3.5cm square. The second pic is as its seen from the top, and the first pic is the flat bottom where it was attached to the glass.

    Are these baby snails or some other type of growth?

    That's a snail. See the little swirls in his shell.

    yeah, I saw the swirls, but why don't I see any critter inside? When I scrape them off, they are rock hard, no "hole" inside the shell, no soft slug inside? Do they only develop a "body" after a certain amount of time?

    Looks like the "door" of a larger snail. Have you had any mexican turbos die recently?

    @Lab - not that I've noticed, but its hard to tell. I've only four of them, and they are never all visible at the same time. I used to be able to tell them apart when I bought them, but now they are covered in coraline so they look the same. Also, I bought shells for the hermits so I can't tell by any empty shells laying around.
    Like I mentioned tho, I've found different sizes of them - one really small that would be smaller than any of my current snails?

    @Amazon and Lab - If my snails are dying, should I be worried? They are not that old, but I would have thought my shrimp would fail first if I had a problem with my tank?

    @ gm - googling operculum...

    Going to see how many turbos I can spot right now...I should have 4...

    Well, for once, all four of them were visible. Two were actively moving, and two when I jostled them wiggled, but I was unable to flip them over, and I didn't want to hurt their feet so I didn't force them. So I didn't lose any snails so far. Do snails shed their operculum as they grow? I found a reference to apple snails, and the whorls are caused by growth, so it would seem not...still reseaching...

    Sigh...maybe I had five snails, lol..

    edit: actually, I just remember that I am finding these things stuck to the sides of the tank high up in the corners - doesn't seem likely then that they are dying, if that was the case I would find them lying on the substrate, no?

    I'm reading now that they may be more sensitive to temperature fluctuations. My tank temp has spiked to 85 with this heat wave, for a couple days - perhaps what I am seeing is a slow die off - losing the operculum may be just the first stage. ??
    We'll see tomorrow I guess if the 2 non movers are still kicking...

    That could be your source. The heat change can be hard on some snails. i wouldnt worry about it. A dead snail here and there is a common sight.
