As for flow within the tank, you want to shoot for 10x -20x tank volume for total flow. You want areas of high flow and areas of lower flow. The water flow throughout the tank should be chaotic not laminar. You want the surface of the water to ripple to promote gas exchange. This is usually accomplished by aiming a PH towards the surface..
If you don't already have one get a QT tank. It's important to QT the first fish you get before adding them to the display tank.
Do not get a damsel unless you plan on keeping it. They are very aggresive fish and if you want them, they should be added last, after the other fish have set up their territories. Please check the fish compatibility guides.
