ID this growing in tank

You can remove it with tweezers or forceps (like tweezers but larger like 6" typically), and a bit of patience. Unless you have a really diabolical strain of caulerpa like I do, that still pops up years after I thought I first "removed" it. I don't know how it does it, but it finds spots to grow where I can't see it. How does it know I can't see it? Weeeeeeird.

Anyhow, you can order forceps off the 'net or go to a home care shop (that's where I got mine, H&H Care or something like that).

Where ya located? If we're local, I actually wouldn't mind picking up a piece of that (trade you for some chaeto if you're interested)? It would make for an interesting macro in a refugium..

I had it in my display...it is a pain in the butt....I manually removed it as best I could and now have none....this is what mine looked like...hey you're lucky, you only have 1 algae to pick off .... I had a nasty bunch of them! (3 to be exact....! Ugh)

Not sure how big your tank is but you could try a Tang or someother fish. I had a Naso tang and purple tang that both ate caulerpa. But Tangs need a lot of space to swim and get big. So would not suggest it if your tank is less then 4 feet.
