Advice Needed. 14 Gallon Biocube.

[biocube14]

I'm a complete newb in keeping a reef tank. I kept FOWLR before but this was a long long time ago. I was given this 14 gallon biocube.

I started this tank approx 2 weeks ago. My friend gave me the live rock, live sand, water, corals and a few inhabitants to start.

Are you guys able to tell me what kind of corals these are and will they do ok in the stock compact flo lighting for now? On the overhang, I glued in the coral and it went side ways after. Will it be ok in this position or it has to be upright?

Current stock:
2 clownfish
1 fire fish
1 fire shrimp
1 peppermint shrimp
5 blue leg hermits
2 snails

I was planning to sell the peppermint and get a small clown goby or watchman goby?

Everyone seems happy so far. I will continue to perform water change once a week at 10-15%.
Also planning to add in more cured live rock and add more corals throughout the next few weeks.

Any other input would be greatly appreciated. I've been reading a lot on the web but lots of mixed info. Just want some advice to get me through the first few weeks.
