Green things under attack!!!!!!!

[aquarist=broke]

Hey people,

Well, I don't even know what these are, but I have a small bunch of them. They were fully green and roundish. A couple of days ago I noticed one of them was turning white and assumed that it was being harrassed. I just looked over and noticed that a stupid snail (who by the way is now in the dog house) ate half of one of these things. Does anybody know that the heck these are?

Help me before I murder my snails..... :twisted:

my (semi educated)guess is a type of macroalgae-(90% sure)it's turning white was prob'ly the result of it's chlorophyll loss as the snail was eating it- caulerpa does the same thing when it dies-i'm pretty sure i've seen this stuff, too, on the occasional live rock-'tubular valonia' is the best descriptive term i can come up with-there is a really good guide book to algaes and macro's, but for the life of me, i can't remember the name-it was a field guide, of sorts- maybe someone else can offer a title?...

hth( -maybe not much )

It is a type of valonia from the pictures. I have a couple of mats of it in my refugium... it grows into quite a thick mat over time. Which makes it easier to yank from the tank.
