looks more like a freshwater setup. the decor isnt natural at all, since the oceans dont really hv plants like that. u might hv nitrate and water quality problem down the road. get rid of those fake plants and replace it with caulerpa if u really like the plant-look.
Do you have any Live Rock at all? ANd is that gravel on the bottom? ALSO do YOu have any powerheads in there??
Bob is right though...lol...My 1st tank started off with lots of fake Fresh water decorations too.....
