Triple coloured seaweed!

When we think of seaweed - just algae - Se often think of shades of green in the water. Some may know of different colours of seaweed or moss, but few know of ont plant carrying three diferent colours.

Chondrus Sripus, aka Irish Moss, appears to have three distinct colours - Red, green and blue! This is possibly due to a trait that helps protect seaweed from UV light. Either way its pretty cool and would be an interesting addition to any aquarium.

I'm curious to hear if anyone is keeping this addition in their aquarium

"When covered in water and illuminated by the sun, the deep red fronds of the Irish moss, Chondrus crispus, reflect some blue light too, providing an iridescent sheen. It’s the result of a series of thin transparent protective layers that happen to be the right thickness to reflect the blue light, points out New Scientist. It’s unclear why the trait may have evolved"
