Thanks, I wanted to try and find a balance between the clean look of white coral and freshwater fish. I need some more green in the background for the fish to hide in when they want but so far everybody has really learned to fit in the coral cutouts when they want to hide.
probably wont be able to keep that coral in too long as its going to raise your ph up very high. Higher than those cardinals can handle depending on your water. Anyways Nice Tank!
