    Nice find. It's a Money Cowrie. They are safe and good herbivores. I have two. You won't see them much though, mostly hides during the day.

    Yellow ring cowrie. Will find them all over Natal.

    Some do call them money cowrie, but the real money cowrie is smaller. They are very close. And the money cowrie is not local. Although you can find the real money cowrie shells on our beaches. Reason is that the old Portuguese ships mostly, used the money cowrie shell as currency on the ship for the sailors. Helped in preventing theft of real money in between the sailors. As the shells had no value off the ship, the sailors had to trade in their shells for real money before departure. Hard to explain loads of shells in front of others who mysteriously lost theirs while sleeping. The shells that do wash up is from ships that where lost at sea. At places the locals did accept it as currency as well, especially entities involved with trade directly with sailors like pubs.

    Lets you think about how many ships where lost around our coasts, if we still get those shells washed up a couple of centuries later.

    Thanks Riaan! I have two that I collected in Balito last year February, and always thought they were Money Cowrie. Nice information about them too, and your photo comparison definitely confirms mine are also Yellow Ring Cowrie.

    Would you say the same info about being reefsafe, good herbivores and hardy applies to them? I'd guess so, since I still have mine, and haven't had issues.

    These are very reef safe.
    If you want cowries, the yellow ring cowrie is THE best option out there. Pity that they are mostly nocturnal. But still very cool to see them at night up against the glass. Do not clean your back panel, they need a place to find food. Daytime they normally hide under a rock somewhere. Due to their small size, they do not bulldoze your rocks like a tiger cowrie can and would.

    They are herbivores, and might eat a dead SPS but more likely the algae growing on a dead SPS.

    They are very hardy and only an issue with big hermits attacking them. Else, if you do notice one upside down, help them up. We do not have the waves as in the sea to help them up.

    The ones I got in my tank is 2 years plus

    I always liked cowries, but have read that tiger cowries are noy really suitable. Read about money cowries, looked for them and found mine. Glad to hear they are equally suitable.


    Luckily I don't believe in a squeaky clean tank, and never clean my back glass. The cowries, other snails, pods and Hector's Goby all graze there. And my pipefish hunt the pods there.

    Unfortunetly there are no cowries in the gulf but next time I go down to Oman to dive maybe I will have the luck to find one.
