Thanks, I am not only a newbie with saltwater aquariums but also a newbie photographer. I've never done anything but aim and hope and I can see there is a lot to be learned if you want good photographs of your aquarium & fish. It's a fairly new (4 months old) 37 gallon that we are converting from the original Eclipse set up to a custom hood, filter, light etc. Once I get the rock rearranged, I'll take some more pix but right now it's not very attractive. I've got to study some other tank pictures to see what arrangement I like.
