Thought I could put off scaping my empty 12gal a while longer... and then, bam, you have to go and show us all how great those tanks can look.
I really like the way that stone is aging under water.
Given any additional thought to a cover of some sort? Have toyed with getting a couple glass panels cut but can't decide if the idea is aesthetically pleasing. Your shrimp problem makes me think it may be worth it.
