    Crown of Thorns are really a pain. But for now nobody know where they come from and where they go.
    Collecting them is an honest try… but useless.
    We had these by thousands in Egypt 1999 and our dive center alone collected and buried in the desert around 2,000+.
    Didn’t help a bit!
    They disappeared some weeks later from 1 day to another by themselves… and nobody could tell me why and where.

    P.S. If you cut off pieces while collecting… these pieces will become new Crown of Thornes. So beware!

    Hello Uli,
    Thank you for your feedback.
    You write “nobody knows where they come from and where they go”. That’s true, nobody knows, it’s mysterious.
    I heard that instead of collecting them one could also inject sulfuric acid (the acid used for car batteries or even more efficiently inject sodium bisulphate.
    Your warning about regeneration from cut-off parts is discussed very controversial on

    Cheers, waebi
