tank running for a week, and a clown in there already?? wow lol fast! or im reading wrong
your liverock, your great your a lil over 1.5 pounds of liverock per gallon like me, its great and it really works well. u can go 1pound but nah i like 1.5.. but also if your doing coral alot of coral come with livrock pieces so u might want to remove 5 pounds.
a mandarin to be honest is out the question your tank needs to be atlease 1 year old and for that size your mandarin would die quick, and if u buy pods for him he will be very expensive to keep
dan it looks real sweet man, but may i recommend not leaning LR on your glass its always good to have atlease 2inches of space between the glass and LR except the rear glass that u can lean all u want unless people r trying to have a walk around tank... reason being is u wont be able to clean ur glass then u will have coralline-algae growth after a while because u were never able to clean your glass...
i say this now so u wont have a headache trying to remove ur rock to clean and stir up stuff plus ull have more viewing area with clean glass and less headache.
