Very nice bro EC....love it! Water is super clear and rocks are arranged in a neat haphazard manner.......swee!
Get some escargots and dump in some shellies....ocellatus maybe.
Maybe u can try taking ur tank pic at night bro...off all the lights and only turn on ur tanks' lights. Effect will be better. Can eliminate those reflections.
U might also wanna try getting abit more slates and position them just beneath the surface of the fine sand over at the bare area. So u can only see the surface but the slate is actually buried. Think it will look nice too.
