Is this toadstool fine?

[Stepheng101]

A week ago I got a clownfish and a green leather coral from petco. The clown is in qt, and I dipped the coral before putting it in. I had the blue lights on the first day and have been slowly turning the white lights on. It is an aqumana 165w light. I noticed there is a little brown growing at the base of it. My nitrates are at 20, and I also have a glass top.

As long as your polyps are out it should be fine. Its hard to kill a toadstool but easy to p it off. Probably a protective layer or about to shed or algae. Nothing to worry about though from the picture.

All of my toadstools have some brown on the bottom like that, nothing to worry about.

After 2 weeks, the coral is retracting its polyps, and I lowered the white/red/green lights. It came out again, but the next day it did the samething. It's polyps only comeout when it is only the blue light. Should I be worried? I lowered the white lights as much as I could.

No worries , It's just pouting over something .

Now I have noticed a new thing on my leather, there is like black lines under the polyps?

Toadstools are pretty tough as mentioned, brown is normal.
Don't be surprised if it gets weird and looks all closed up and spider webby, they will do that before a big growth spurt, usually trips people out first time.
