Hi all,

I seem to have an algae called "staghorn".. sort of like a branching version
of thread algae.. thicker strands than thread too.

usually they are pale grey-green.. but few of the strands started to turn
pink (almost fuscia-color). kinda pretty, but a it disturbing (unnatural
color!)

what does this mean?

Likely it might be dying. It's a red alga and usually has grey color
but in stressed portions it will turn red.
Phycoerythin is the red pigment.
