    Just wondering! Does it have to do with a calcium amount, so it varies from tank to tank? Cause that is what I was thinking...

    They molt as they get bigger.
    Mine also molts every 2 or 3 to 6 weeks.

    Iodine is very important dor the health of shrimp, they need the proper amounts to shed.
    Mine shed about twice a month.-Michael

    Mine seems to shed with the cycle of the moon. Lately it's been within about 48 hrs following the last day of the full moon.

    Iodine is only need in very minute amounts. It is called a trace element. It is poisonous in larger amounts (this is why it is used to sterilize for surgery). It is neccessary for shrimp and all animals in very minute amounts. Shrimp are able to incorpate excess iodine into their exoskeleton and then shed to get rid of it. This has led to the belief that it helps them molt. It really causes them to molt to rid their bodies of toxic amounts.

    Every few weeks is normal.... but also note that overly frequent shedding has been looked at as a sign of stress..... yes you can shed TOO much :)

    Is it unhealthy if the shrimp very rarely molts?

    It might molt and you just don't notice it. Sometimes they molt in a little cave, and then hang out there until they grow another exoskeleton. They also eat the molt because it's rich in calcium.

    Younger shrimps molt more often than older shrimps because they are growing faster. The molt is initiated by growth hormones not by iodine. Iodine aids in a successful molt, but does not initiate it.

    I"ve read about the excess iodine shed as well in addition to the growth shed.
    Where do we go for a ruling on this?

    I'd heard about the iodine with the molts... but if they eat the molt wouldn't that be re-consuming the iodine they just shed?

    They are not likely to eat a molt that was caused by excess iodine. Molting or shedding the exoskeleton is normal behavior for growth and repair. Molting due to iodine will be in addition to this normal behavior. They will shed more frequently if you dose iodine in order to help rid the body of the excess.

    Am I totally wrong or doesn't the IODINE change chemically within the shrimp? Doesn't it have to be broken down and "Reconstituted" to be able to be "taken up" again by another animal?

    Adding to what Reefjitsu posted, a molt due to high iodine would be abnormal, artificial and un-natural, IMO, stressful on the animal.

    Don't make me come over there!:lol:

    How long does the process "usually" take? From molting till the new shell has hardened. One of my new skunks went missing a few days ago. Today I found an empty shell I'm sure there wasn't any shrimp in it at least. I'm hoping the stress of the new tank caused it to molt & it's hiding out. I would think if the shrimp died the brittles would have eaten it right away shell & all.

    Usually they molt overnight. If you found an empty shell the odds are that it molted and hes hiding out.

    Each body requires very small quantities of iodine daily. Whether shrimp, crabs, fish or coral, all they need iodine for a healthy life cycle.
    In the sea iodine comes only in very small quantities as a "over dose" is excluded. In the “standard” aquarium is sufficient iodine present if you changes every week 10-15% water. There are exceptions. If for example many gorgonians maintained ore if you use aktivated carbon. Activated Carbon cut the water almost everything iodine. In this case, little iodine doses, a few drops approximately every 2-3 weeks, is sufficient.

    BTW. Young shrimp molting much more common than adult animals. In the first year of life molt shrimp initially almost every week, then every 2-3 weeks. Adult shrimp molting every 4-6 weeks.
