Hi all,

Is the colour of the BBA related to temperature?

Not sure, I know for the marine reds that they tend to be redder in low light and darker in high light, and that if the red seaweed from the lower shore end up higher up the shore (in a rock-pool for instance) they tend to bleach white.

The local LFS has blue BBA. Thought it looked quite cool. 8)

Colour seems to be species specific.

Different species also have different preferences for temperature and flow.

It seems blue BBA has invaded Japan recently probably "through the vector such as ornamental macrophytes"
