I won't even comment on the tangs in there, because I am sure other will(assuming this is a 55gallon as your profile states). However the tank does look nice and I like the rounded side. Just a suggestion, it looks like you have a air stone or bubble wand in your tank, take it out because it is somewhat unnecessary and will create salt creep on your lights which will more or less destroy them(if you dont have a top between the tank and the lights). Other then that, nice tank.
