Well, this is very hard to answer. As it depends of course on your personal taste, especially when it comes to the look and the beauty of marine macroalgae.

We love macroalgae, so we see the beauty in almost any macroalgae species we have. But we know how friends react when they see our private reef tank with the different marine macroalgae. 

There are of course some macroalgae which look really stunning in the reef tank, and we would choose them as our favourites when it comes to the beauty of them:

CODIUM

BOTRYOCLADIA - RED GRAPE

OCHTODES SP.

HALYMENIA DURVILLEI DRAGONS 

GRACILLARIA CURTISSAE

HALIPTILON SP

CRYPTONEMIA CRENULATA

HALIMEDA INCRASSATA
