    Has anyone ever kept this lined bubble shell or rose petal bubble shell?

    They feed on burrowing polychaete worms, so should survive in my sump if there is enough food for it. I wonder how much food it requires?

    Why keep something "pretty" in your sump? Seems like a slummies idea. I've also "thought about" keeping Hydatina in the past and have always settled for more herbivorous local cowries.... Since they generally roam fairly widely and fast at night, I am fairly sure that they will run out of food in a normal sump and probably only chow down on specific types of polychaetes (and I doubt that they eat bristle/fire worms...).

    You're right. All that I've managed to learn so far is that they eat burrowing polychaetes, but even there, there are tons of different species.

    Did you collect any cowries in the Eastern Cape?

    Yup, I tend to target the more herbivorous ones as I like having sponge in my tanks. I've had success with annulus cowries, serpent's head cowries, and erosa cowries, but limited success with bigger cowries such as tiger cowries (Cypraea tigirs ) etc.

    Here's the last giant tiger I collected in the Kei - shell is bigger than my fist. Pic is kak as was taken with my first UW camera.

    Sorry Mudshark
    But it will die eventually. Its very very beautiful. Eat mostly Spaghetti worms. Maybe on a old established sump, with big DSB to sustain it.

    And Cowries, I like the Yellow Ring Cowrie, not sure if they are down in PE. But they do not grow big. Stay small, can have a number of them and they are excellent grazers. I got 6 in each tank. And due to size, they are not that likely to cause rock falls. Pity they are exclusively active at night.

    Yup, that's the annulus cowrie (Cyprae annulus), I've seen them south to Mossel Bay.

    Rich, let me get this right, you have a devil damsel in a spot and you keep it secret, :whistling:

    eish, you PE puddle jumpers are not a full rock pool.

    Broder, sorry to highjack, but I am sure you will understand
