    Caulerpa Sertularioides


    Caulerpa Sertularioides is a very beautiful macroalgae which develops upright feather or fern looking blades, which can reach a height of up to 20cm. It can be sometimes mistaken as Caulerpa Taxifolia but it looks more filigrain. It grows well in the substrate but prefers more hard surfaces to attach to.

    Premium Marine Macro algae for the Planted Reef Display Tank & Refugium for sale on Live Algae UK.
    Your 1st choice for clean Marine Macroalgae from Fish & Copper free tanks since 2014.

    The blade colour of the Caulerpa Sertularioides macroalgae varies from darker to lighter green shades, but normally it is more a lighter colour as shown in the picture.

    The Caulerpa Sertularioides macroalgae grows opposite to the Caulerpa Taxifolia more in shallow sandy areas, protected between mangroves areas or shallow reefs and does not like very strong lighting.

    Caulerpa Sertularioides is more palatable than Caulerpa Taxifolia and therefore we recommend it as an additional natural food source for herbivore fishes. We recommend keeping it in a safe place until you like to offer it as additional food to your fishes.

    The commonly called Fire Fern or feather fern macroalgae will easily attach itself, but it can be to start with as well glued ( we use thick cyanoacrylate super glue ) to rock where you like to have it.  It will attach itself with Rhizoids to rock or into the substrate and as it is a fast-growing macroalgae species it can easily overgrow the rockwork when not kept restrained.

    Like for most marine macroalgae a higher level of nitrate and phosphate, in addition to the supplement of Iron, Magnesium and Trace elements will improve the growth of this live algae.

    If the macroalgae is not growing as expected a special formulated fertiliser for the marine aquarium can help to improve the growth of the macroalgae. Please find a selection of supplements for the marine aquarium HERE   

    This is a very rare available live algae species, and we are happy to offer it to you. It is so a much more fragile macroalgae species than for example Caulerpa Taxifolia, and we recommend to split it more often,l as it might suddenly die off, and so you will keep the species more healthy.

    Please note
    Our macroalgae are from fish free macro algae tanks, although we use sometimes pictures for demonstration purposes only which will include fishes, seahorses and or corals. 
    We do our best to quarantine, treat and remove any unwanted hitchhikers, parasites etc from our macro algae but we can not guarantee that the algae are completely free of anything unwanted, not limited to Copepods, Rotifers etc. This is simply because that sometimes eggs, spores, etc can remain viable but not visible and hitchhikers can still stay hidden, especially in dense algae structures, despite our strict quarantine efforts. 

    All macro algae will be thoroughly dipped in a professional solution to deactivate hitchhikers as good as possible before posting. If you don't want this, please send us a message together with your order.

    We highly recommend nonetheless that you properly quarantine anything new before adding it to your marine tank.

    We aim to offer you the healthiest and best quality macro algae on the market, therefore, all of our macro algae comes with a 100% Satisfaction Guarantee.
