Brown Algae - New Tank Syndrome

Almost all my tanks have finally cycled. Right around the time the saltwater tank cycled, I noticed something brown in the tank. It was like a brown snow had fallen. From looking online, I figured out that this is a brown algae known to occur commonly when a saltwater tank cycles. It is actually made from diatoms.

If you look to the left, you can see where I tried to use a vacuum gravel and water change to get rid of it. Looking at the tube while doing so, I noticed that it was not coming up. All I did was mix it into the substrate - and it definitely did not come off the rock. So I went to my LFS (Local Fish Store) to find a better way to deal with it.

Since my tank was finally cycled, I could actually start adding fish, corals and inverts. I had read there was a certain fish that would munch on the diatoms. Well, the fish I had in mind was not in stock and probably would not have been a good permanent resident. But the store owner did recommend some snails which also eat diatoms! I got 3 different kind of snails and they got to work right away.

I also got two inexpensive coral fragments. One thing I didn't realize is that corals contract when stressed. Once they were bagged, it looked like they fell off the stand and disappeared. They were just contracted. It didn't take long once I put them in the tank to see them start to open again. They are not as open as they were in the frag tank at the store yet, but they are getting there.

I was not sure how long it would take, but in just about an hour or so I saw it start to open again.
These are my first corals, so we'll see how that goes. The green one seemed to be swaying - and I was told to put it in a calm area of the tank. So I moved it - and it scrunched up to a tight little square when it was moved. Just a few minutes later, it's starting to open again. I'm going to do a bit more research on what type of corals I have and how to care for them. There's so much to learn. I have a feeling the corals may need to be moved again once I find out more. Looking at where I have them now, they may not get enough light in their current positions.

And the one fish I added to the tank is a Solar Fairy Wrasse. It's very beautiful and seems to be getting along with the two clowns. It really likes going in and out of the spaces between the rocks. However, at the end of the night it seems to have disappeared. I found that they spin a cocoon at night so parasites don't attach. It's probably sleeping somewhere and will pop up in the morning.
