Pencil Cap Algae (Penicillus capitatus)

Unfortunately, all specimens of this macro-algae have withered away.

Unfortunately, one of the pencil caps was over-grown by caulerpa and has since disappeared. The other specimen is still hanging on and seems to be getting better. I have added two new specimens along side it.

Both specimens continue with their steady decline.

Both specimens have steadily deteriorated. However, they haven't shed any "leaves".

Pencil Cap algae is a calcified green algae that grows to about 4". Most herbivores will not consume it because of it's high mineral content. It requires a fine, deep substrate.

I have just received two specimens of this macro-algae and they appear to be suffering shipping stress (one markedly more than the other). I have been advised to expect them to die back dramatically before making a full come back.
