There is no such thing as red grape Caulerpa, it would be a species of Botryocladia.

Could be that (botryocladia). There is a desirable species that has diminished stipes and is mostly air bladders as your photo suggests. Most desirable species are prostrate and have visible stipes. I have a few species in my tank, including a common pest species in my sump that tends to float. That pest must be effective at releasing spores because new clumps show up every now and then (where as the 'desirable' species grow vegetatively off individuals).

This is definitely NOT Botryocladia botryoides, which has branches and grows high.
Probably Botryocladia skottsbergii aka red Valonia or red bubble algae.
If you ever heard about green Valonia... this algae is quite invasive in a coral tank.

Still ok for a marine planted tank though.

I have never seen Botryocladia skottsbergi. Reefcleaners info article list it as a nuisance algae. Thank you for the latin name, however, I do like
Red Valonia.

Thanks for your kind words.
I do think it's nice to share with people abroad about peaceful macros in these nuclear days.

Anyway, i like this algae too, but wouldn't recommend it for a... peaceful coral tank
