    Specifically Caulerpa taxifolia

    See the 24 hour lighting for the refugium being advocated as the cure against going sexual. Where the older rule was a reverse lightning schedule to your display system.

    So my question, had anybody experience this behaviour on taxifolia? I know racemosa does go sexual easily.

    I have Caulerpa sertularioides in my refugium. I am only running my sump at the moment, refugium gets 12hours light during the day. It has never gone sexual on me.

    Taxifolia seems to have flatter branchlets than sertularioides. Ive seen these two growing together, Taxifolia looks a lot more sturdy, sertularioides more delicate.

    Just once. It's definitely more stable than racemosa.

    It starts humping your fish. :tt2:

    It goes white and releases spores into your water and then dies. Can cause an ammonia spike/bacteria bloom and in really bad cases (ie. if you don't have a skimmer) can crash tanks.

    I have some / lots of caulerpa brachypus in my sump. It got into my tank as hitchhiker. I managed to get rid of all of it in my DT but left some in my sump. It really grows extremely fast and been coexisting with Cheato for more than a year now without a problem.

    Hello Riaan, just a word of caution wrt feeding the stuff to your fish. Apparently there's some toxin in them which can cause problems for some fish. I think you've got sertularioides. Taxifolia appears to have longer leaves..
