Something about your tank - not sure what - seems a little off to my eyes. I am not sure if it's a spacial thing (because you have the sides empty, and maybe I am used to rocks going from side to side?) or maybe it's because your tank looks like it has no water in it some how... maybe some actinics or 20k bulbs would correct that for me.
Don't get me wrong, it's a nice tank, the fish, coralline, and rics especially, just something feels missing for me. Does anyone else agree?
