ID on a couple different things.

Pics are hard to get...but I'll try.
Did some research and found this on these forums:

The thing I have in my tank is what Tizzo posted in post #70. I wasn't able to find any other information about them. Are they good/bad?
Also, I have something that looks like a Colonial Hydroid?

I read that these are bad. Gonna try to post pictures of these things soon...just wanted to get feedback in the meantime.
Thanks.

Ok. Well, I wasn't able to get a pic of the second thing...but I know for sure it looked like a 'colonial hydroid'. I blasted them with lemon juice just as I did the two apitasia things that were next to them. They look like they are dead...but I'm sure I will be able to tell for sure tomorrow.
As for the thing in that thread (post #70), I see that I have two of them...and I'm debating blasting them as well!
On one end, I have read that they are good and they are a kind of mushroom, on the other end I read that they are bad and are an anemone.
