Lookin good. I like the rockwork. One recommendation I might have is to get rid of your mandarin goby. If the tank has only been set up for a couple months there is really a small chance that the madarin will live. They eat pods which your tank is probably not yet full of...............they eat em quick too. Other recommendation would be to put another power head in there. At least one on the bottom of the tank in the back.......two would be better. I can see some serious algae in the spots that you did not clean and that is probably due to the lack of flow in there, not that you don't have some flow (filter,skimmer, powerheads). As I said, looks nice so far.
