    What implication/effect would a bi-valve (commonly known as Rock bait on the Natal Coast) have on a marine tank/sump?

    not very easy to describe - these are usually dark brown rock looking growths. they grow on the rocks. they have on each side a horn - holes in the horns - if you touch it, it contracts and squirts water out of the holes - fisherman usually cut them open and take out a red orange meaty substance which they refer to as rock bait. these 'bi valves usually are all over and if you remove other items from the rock these organisms are stuck to the rocks and squirt this water out. unfortunately no pics

    They are ok in tanks, but generally don't survive, similar survival rate to mussels and oysters.

    They need loads of super fine Zoo & Phytoplankton to survive.

    Ok found my "A pocket guide to Bait Collecting in KZN"

    Under Red Bait

    Legal Capture Method
    By hand, the base is to be left

    Reminder
    The marine worms that are found in the base of the red bait are illegal to posses & utilise
