I actually think it looks a little bare. Maybe you should re-add some of those rocks just to cover up your equipment a bit? Like make a couple of piles on the ends to cover or partially cover your equipment, while still leaving the mid section open? I dunno, just throwin it out there!
added some rocks, looks better allready.. my head fish the peacekeeper died got stuck between rocks, threw the whole order of the tank out - ended up with some bruised fish from fighting. im very carefull now where i put my rocks.
