Need help ID macro that came with my shrimp

[BryznNguyen]

Hi everyone I bought a YCBS today and this came in the bag unsure if it’s something I should keep or throw

looks like Caulerpa

Probably Caulerpa brachypus, also known as sea mustard and mini Caulerpa. This is a very uncommon Caulerpa species that I have found to have a very low risk of going sexual. It is slower growing than my Caulerpa prolifera and Caulerpa paspaloides and can form gorgeous carpets on the sandbed and rocks, though still has the potential to become invasive (@dvgyfresh had a Caulerpa brachypus infestation once). It is probably a good refugium algae.

Wow it looks pretty neat ! will my snails and hermits eat it if it put it in my display? I only have a 20 AIO and the chamber isnt ideal since it doesnt have a light over it

I haven’t seen anything attempt to eat it before in my system. What species of hermit crabs and snails do you have?

I got that in my system once its really hard to get rid of once it attach because it can generate from a speck. Its not a big deal if you are planning a macro tank, it looks really nice if you trim them like a planted tank. but if u want sps or high end coral, they will grow over them. I have not ever had anything eat them too.

Caulerpa prolifera
Snails and crabs don't pay attention to this algae.
Grows a lot - in tanks which are rich in nutrients.

Not C. prolifera. This species grows taller than C. brachypus. and is not serrated like C. brachypus or the Caulerpa in the picture. You might have Caulerpa mexicana.
