Hey George,
Long time fan, first time botherer.
Just wondering as well why you chose the cardinals.
I remember in last months issue of PFK, with the large open Iwagumi tank, it mentions that contrasting colours should be avoided in Iwagumi.
Don't get me wrong, they look fantastic, and I much prefer them to anything that would usually go in there, but is that the reason why? Because it's different? Were you trying to spice up Iwagumi considering all the blandness you find these days?
