Pitho crab vs caulerpa !

[Patx]

(Pitho mirabilis)
I was skeptical but I tried it anyway.
I don't know if it will help against what appears to be derbesia, but it will certainly help against Caulerpa serulata.
I've been trying to get rid of this caulerpa for 10 years...
I guess, less chirurgicale manual pulling will be necessary!

Next target (i hope)

Another algae on its menu.
(Rhipidosiphon javensis)

As for my "turf," well...
it's difficult to really confirm if it eats this algae or "other things trap in it."

But, For now, it is consuming 2 types of algae that nothing else has eaten before.

I have never heard of that one and would love some! I love the look of it
