couple IDs please

[sirrealism]

I picked up a few Zoas and need IDs if anyone knows. Thanks in advance.
First one has not colored up yet. Hoping it will get better colors

Second one seems to have the same issue

third one is not as blue as the pic shows. Really all of them are not as blue as pics show but this one looks closer to black
Then i have a sponge growing on one of my LPS. Any ideas what I should do.

I will retake the pics tonight with the blues turned way down so the colors come out better

first is probably fire and ice, the others don't know, I would remove the sponge as it'll eventually smother the LPS or any coral for that matter

Thanks Pedro. I will remove the sponge.
