Coraline Algae In Different Colors??

light intensity can change the color to a point.you can have yellow,tan,green,red,purple.if you want more than one color you need more than one kind of live rock cause in nature you don't usually get different kinds intermixed on the same rock.thats why its nice to get differnt kinds of rock mixed together to get several colors

 

coraline can depend on the spectrum of lighting pink, red, purple, in lower level areas of light it can even be blue, green, yellow it can come in several colors.just remember its a high calcium alge and needs lots of it to grow

 

There are many varieties of coralline including white. Our display tank is covered mostly in purple, pink, a little green, and a bit of white. 8)

 

i heard they could also be snail eggs.

 

The small white spots are definately worms and their little shells. I used to get them all of the time.
