Yes tanks are like TV's, they are big at first. After awhile not so much.Yay. Getting the new big tank is always exiting. And the feeling that the tank is massive is always great. I have always found that after a month or so it stops feeling large, and starts feeling small (no matter the tank size that it is), which is a shame.
How are you planning on filtering that beast, and what are you stocking it with?
