What eats these algaes?

[mark]

Had Lobopharo so tried both the Black Long Spined and Tuxedo urchins and neither touched it. Dealt with it by tweezers and a dental pick.

Halimenia? See referances for Halymenia (red) and Halimeda (green).

For Halimeda, nothing I have touched it either (Purple and Regal Tangs, Foxface or the urchins) but not really a problem algae and easily controlled by manually pruning. Found pinching with my finger nails between segments stopped the weeping.
