    Ok I have had this GHA for some months now or almost 7 months & seeing something strange of late. Now the question, if GHA is left for some time is it possible if it could develop into a sort of macro algae ie. Feather Caulerpa C. crassifolia as such? The reason why I ask this is because I have never had any Feather Caulerpa C. crassifolia in my tanks ever & I'm seeing little feather looking plant & a toad stool looking plant & both run like an ivy vine. Could anyone could please explain what the hell is going on there?

    Thanks in advance

    well it cant change, but i have see similar, it could be that GHA has many different strains.
    have you got pics?

    Do you mean that it has matured, into something bigger?

    So you recon that it could just be a different strain of GHA right? What confuses me is that runs like grass does with 1 stem & anchoring at every feathery leaf/toadstool leaf.
    I left the GHA not out of laziness but to see how the algae actually develops & so far it's been very interesting. I am getting a bit gatvol of this GHA so I recon I should cook the LR with is a long process but at least the GHA will be gone & the rock is still full of life. Thanks guys

    I certainly think it's Bryopsis. Have you read up on Prodibio?

    The one with the disc shaped leaves looks like caulerpa racemosa to me and the other one looks like fern caulerpa. Ummmm.... I have a camera for sale dude;)

    Bryopsis is a much finer leaf and doesn't send out runners. A tank will constantly go through algae cycles throughout it's lifetime as conditions favour one or the other algae type. I've found that changes normally occur around about spring. The macroalgaes that are taking over from the GHA are certainly prettier! They're also easier to remove when they become too dense. Don't let them grow into unreachable areas and into crevices if at all possible. They can then become a nuisance.

    Both look very similar. Do none of the bryopsis species send out runners? If this is fern caulepra, is there anything that eats it?

    To be honest, I thought that there was only one variety of bryopsis. I only know one from my tank and have never heard of other subspecies, so I'd better retract my ID of fern caulerpa until I've checked that out. Thanks for the heads up chas84:thumbup:

    I've managed to find a few varieties. Busy researching it for an article, and coincidentally I have it in my tank :( I guess this experience will add more substance to the article hey...

    Bryopsis corticulans
    Bryopsis corymbosa
    Bryopsis halliae
    Bryopsis hypnoides
    Bryopsis indica
    Bryopsis pennata
    (Bryopsis pennata var. leprieurii )
    (Bryopsis pennata var. secundata)
    (Bryopsis pennata var. secunda)
    Bryopsis plumosa
    Bryopsis ramulosa


    It seems like such a mission to get rid of, hope I find a solution though.

    Doesn't really matter IMO. If you like it, leave it but make sure it doesn't trap detritus or steal light from your corals. If it grows at an alarming rate, rather remove it. If you don't like algae, then control it with the usual measures, starting with reduced feeding, wet skimming, correct lighting and ensuring that detritus doesn't get trapped anywhere(including your substrate).

    Nice camera. Are you a surfer? You could even strap it to one of your fish. Imagine the awesome vid when you eventually get it back.

    I recon I should remove most of it cuz it is stealing light from some of my coral.

    I really dig that camera & it will come in very handy while Kiteboarding or diving. lol if I had to strap that to any of my fish they won't be able to swim but ja if strapped to a Great White oh yes imagine a 1 on 1 breaching for a seal dinner. That would be just awesome but to get camera back would be another thing.
