It looks like a form of bubble algae. If it looks rather like a small banana, that's what it is. You can look at this ([Only Registered Users Can See Links.])to see if that's what you have, and what to do about it.

i think it is a type of algee, but not bubble, i have got bubble algee at the mo, and it looks nothing like that.
