I have a 29 Gallon that has some beautiful brown gouramis in it. I'm thinking of moving the zebra Danios into the 20 gallon (there's two in there already). Here's what I want. I want this 29 gallon to have fish with very earthtone colors. I'm thinking browns, gray, and beige. I kinda want the fish to blend in with the gravel, plants, and some driftwood. What do you think? I'm going for subtle but unique.
