    Macro algaes on Live Rock

    My live rock has been in for 9 weeks. I have some interesting macro algae growing on the rock. The first I have been able to identify. It is Padina sanctae-crucis. It is a califying algae. The largest plate is now approximately 2" and I got the info from Padina Algae Info Source



    The following algae I have not been able to identify. It has a thickened "branch structure" with fine hairs as "leaves". Bith the Kole Tang and the Lawnmower Blennie are eating it, so it cant be half bad. Any ideas on what this may be?



    Thanks

    Nice, Padina needs a good supply of Calicium and optimal water quality like Halimeda.

    I have a large amount of Halimeda opuntia growing and its really a beautiful Calcareous algae.

    The other pic isnt to clear but is it growing? cause it looks dead to me,the left strand of Algae in your pic seems to be Dead feather calerpa,but the center looks likesome that I had on a piece of live rock I got this summer but died slowly I think it was dead to start with but slowly withered away.

    Robin,

    Thanks for the reply. Padina is growing quite well. It has not taken over, but it has grown in some nice little clumps, usually one dominent plate and several smaller. I even have an astrea snail sporting it on his shell. My calcium is above 400, so it is getting the calcium. Last water test had all parameters at 0, so it appears it likes its water condition.

    The algae in the second picture is greener than the picture shows. It appears to still be growing. I have only really noticed it the past few days, since I got the Kole Tang. I am going to keep searching for identification.

    The filament algae phase seems to be rapidly declining now. The calerpa growth also seems to be slowing.

    Looking at it closely it looks like some form of Rock Moss,like Lichien.Looked for marine moss and found this under the sub species of chondrus.

    Take A look

    Robin, the Rock moss is similar, but I cant really see the "branch" structure. However, it does give me something else to look for. The branches (for lack of a better term) on my algae are thick and round. Reminds me of some bonsai trees I have seen.

    I also looked up Halimeda opuntia after you mentioned it above. I also have this in my tank. It is an attractive algae.

    Thanks Robin
