Gravel: Great and Small
I'm down to the part in Aquascaping of picking out the gravel. I know I like natural looking substrate, but I'm not sure if I should get larger pebbles or small-ish. Is it just a matter of opinion, or does it have a larger ecological impact? I'm planning on stocking the 75 with Mollies, Platys, Guppies, Cory's, Tetras etc.
What say you?
