    as the topic says, what is the average?
    how long have you had your shrimps, urchins etc?

    My shrimps haven't lasted for more than a year...
    But my porcelain & emerald crabs ive had for 3 years & still going strong!
    I have a turbo snail for 2.5 years now, & when I got him he was already quite large & probably older than 2 years.
    Long spine urchin for 4 years
    Blue legged hermits for 2.5 years +

    thanks..

    i have managed almost 2 years with my shrimps, i think they have a short lifespan...

    this is another reason why we need to push the limits for captive breeding, so that we can know the age and expected lift left in our animals...

    Ok, let us start all over again. %&#%@& signal in the bush......
    03 Boxer shrimps... About 2 years and lady I got it from, also had it for about the same period.
    Urchins.... About 2 years inside jo jo tank and still small compared to ones I see when diving.
    Hermit crab.... Had it since 2007, gave it to a friend and it is still going string, although it is much bigger... Make sure they have enough empty shells... Big ones...
    Brittle starfish....... About 2 years and believe me, it is bigger than both my hands... I am sure they would be able to catch a fish if they want to... Fortunately have not happened yet....

    Cosidering that some female spiders live up to 30 years I don't see why most inverts can't have a seemingly long life. In terms of molluscs, it takes a few many years to reach sexual maturity. Pearl producing oysters are a great example of this.

    cleaner shrimps last about 2 years. Actually they last only a certain number of moults. The faster they grow, the more they eat, the shorter their lifespan. :(
    So when you buy cleaners, get the smallest ones they have. They will last a lot longer. At the end of their lives, second last moult you can notice the feelers are not that straight anymore. That is their old age symptoms.

    Oldest Bristle star I got is 4 years. He always hide so not sure on its actual size.

    @RiaanP so the less food they get the longer they survive?? LOL

    Mine are 3 Years old now... They almost look like dwarf lobsters because of their size.

    yeah, I know.

    I think the tank temperature also plays a role.

    And make sure when you got them. Time flies when having fun.

    My cleaners are about 3 years old now too, I've had them for a year now, and got them from a guy who's had them for about 2 years. And we've had a boxer shrimp for 2.5 years now, he was already quite big when we caught it in April 2011.

    They are highly sensitive to changes in their environment and water chemistry.
    In an aquarium they are often short lived because the aquarium keeper is unable to maintain constant conditions of high water quality.

    Many even kill them the minute they get them home from improper acclimation procedures. As a result, they have a common lifespan of 3-5 years in the home aquarium.

    In smaller systems where there is more fluctuation in temperature and water chemistry, they are shorter lived than in larger more stable aquariums. And again, just throwing one from the fish bag into the tank without acclimation and it might instantly go belly up! In the smaller systems, or younger systems, it might die in a year or two just from silly mistakes or temperature or pH fluctuations.
