Assorted macro. Some of that emerald crabs will eat. Tangs some. Urchin will keep it mowed down if you pluck it out. I like it. Good for your tank if managed. There's several guys here that can be specific with identity. Good luck!

Likely Avrainvillea; sadly, there isn't much information on this algae online.

P.S. I doubt it's Udotea (Mermaid's fan), since species of this genus are generally found rooted in sand.

Some looks like paspaoids. halimeda and others cactus algae often found in carribean sandbeds.

Personally, I am not seeing any Caulerpa paspaloides, though I have found that Udotea can sometimes grow rather "feathery." It's definitely all calcareous green macroalgae (which is generally desirable), though it seems to be a single species.

who could eat this calcareous algae? a sea slug?

thx for your help

You will find most of these leafy species are either non-consumable by cleaner crew or contain toxins to prevent them form being a meal. You may have to cut away with a paring knife and utilize a dental pick or small crochet needle to pull remaining. If anything would eat root structure, likely an urchin

My quote- looking on a phone- I specified looks like.

Correct. The areas I pulled by the root are collateral damage now as urchins pass. Same with crabs. Once it forms a lobe or leaf it's gonna grow. Put one of those rocks in the sump and let it grow.

Absolutely
As long as there are roots. It will continue to grow

Hi, have you managed somehow the outbreak of that algae? I have exactly the same and nothing works in my case. After toothbrushing it spreads over the tank
