Green noodles

[Jcroy]

Hi everyone,
I have had my 125 for 8 months. It contains 1 black and white clown, 2 different wrasse, 3 fire fish, 2 bta, and sea hare. In the last two months I have found this greenish noodles growing om my live rock. It looks like ramen but green. Not sure what it is, help...

Perhaps Neomeris sp. (Spindle Weed), but without a picture it could be just about anything

My rule of thumb is that if it's a weird growth, it's a sponge.

Chaetomorpha looks kind of like Ramen noodles.
