    I looked at my tank with a flashlight yesterday and after seeing normal large and smaller pods found tiny ones...

    More like bugs than normal pods, size 1/2 mm to 1 mm, look like mini-armadillos in shape and have 2 very small antennas in the front.
    Very small size but looked like that have a shell or a pretty hard-looking body.
    They were all over the corals too, especially zoa and montis. Lots on the sand and rocks.

    When bright light touches them - they can detach from glass and either swim away or get moved away by the water movement.

    Is that a common bug or something bad?

    Sounds like an amphipod, not a bad thing.

    I don't think so, even though I have a lot of amphipods too.
    I looked through pics of isopods, copepods and amphipods and could not match it.
    The bugs are much smaller and have no visible legs, not c-shaped. They have unibody, no evidence of body segments.

    p.s. Assuming I had jellyfish in my tank for a long time, I'm not surprised this could be something weird.

    Then your armadillo reference makes no sense since they have a segmented shell *AND* legs ;)

    I highly doubt you had "jellyfish" either.. most likely just a medusa form of something else, that is fairly common.

    No telling with out a pic, good luck

    Thanks for comments Gresh. I meant that they have armadillo-like shape. Kind of like elongated egg shape.

    I know hard to describe. one more pic that is closer:

    Looks like you find the id for yourself. There are about 6,000 species with a variety of feeding strategies - detritivores, algae-eaters, micro-grazers, plankton feeders, filter feeders, scavengers, predators. A few - few enough that you don't have to worry about it - are parasitic on other inverts.

    I think they're called bedbugs :p
