Random salt water questions

[posenergy]

I have a couple random questions about my 20g..

I have some hair algae growing and it's been touching The frog spawn.. The coral doesn't seem to be bothered, it opens normally every day.. But I just wanted to make sure. Here's a picture

I've also seen this black.grow in the past few weeks
Any idea what it is?

Also what are these white things on the back glass? Are they harmful? They've been there for a while..

Frogspawn isn't going to be bothered much by algae. But you should still remove the algar as it spreads very quickly.

The black tube is a vermetid snail. Its a harmless ish filter feeder. They only problem is they can irritate stony coras if they are nearby

The white swirls are spiorbid worms. A completely harmless filter feeder.

So I shouldn't bother moving out anything but the algae?
