    What kind of creature is Coraline ?

    Notice different colours or shades of red going through to purple.

    Can this colour be determined or changed ?

    The coraline we normally see is the pink variety, you may see green and dark red too, i have never sen yellow or blue, it may come from deeper water varieties.

    Hi Warr - Just to add - the color that grows in our tanks, depend on what spores are available in/on the live rock, and also in the water.... The coloration of the corraline algae will also depend on the type and amount of light (and also the length of photo-period) that we have in/on our tanks. Eg. I have had flourescent orange corraline grow in my tanks, on the bottom of certain live rock..... BUT they only grew where there was extremely low light.... The most common I found to grow in my tanks, were very deep (wine) red, purple, pink/light pink, green and white......

    The growth of corralline algae depends on the absense of phosphates in the water, the high'ish alkaline (must be high enough), as well as the high'ish calcium levels (must be quite high - higher than at least 380-400) before corralline really start growing well.

    BTW: it is also an indication of maturity in our tanks, and also corralline is classified as MACRO ALGAE (but not completely plant-like)...

    Mekaeel - what did you think that parrot-fish lived off on the reefs? BUT, unfortunately parrot-fish are indiscriminate - they also break off some great pieces of coral to chow....

    No the tags won't, but there are some urchins that do - but they can be a little destructive.

    Urchins, Way way to advanced for me. I am still trying the softies and my new LPS. I get an urchin when I build my 3000l tank.

    My Tang is eating something, keeps picking away at the LR. He is such a PIG, eats all day.

    Hi Warr - No - Tangs won't eat it..... You will unfortunately have to "scrape" it off the tank's glass..... Not the most fun thing to do ;-)

    BUT, I would also not keep sea urchins with LPS - they could do too much damage (their spine causing major damage when it "pricks" the LPS "skin".......).

    You are lucky that your tank is already starting to show signs of corralline algae growing..... Some people keep their tanks for close to a year, perhaps longer, without getting corralline to grow. Seems that you have a "nack" for purple fingers too :)

    What purple plague? coraline is a relatively slow growing hard algae, which is usually regarded as a pleasant addition, you don't mean cyano do you?

    Dude it is all over my rock, I now have 70% of LR is purple, i even have it on the glass.

    And it is not cyano, have had that problem already and blasted it to oblivion.

    Don;'t you find it weird having a PINK tank ?

    That's the ideal of nearly all reefkeepers to have plenty plenty corralline algae in their tanks. The corralline on the rocks helps stop nuisance algae growing on the live rock. Also, it makes the live rock look REALLY nice! Some people like scraping the corralline algae off the glass of their tanks - others like to keep it there (I am as straight as an arrow, and I like the look of pink in my tank :thumbup:)
