I decided to set up an old 10 gallon tank I had sitting around. I wanted to do something colorful and fun with this tank. This is my first time using sand. The tank is still cycling so I won't be adding any fish any time soon. I am trying to get some ideas for colorful fish for this tank. I was thinking maybe something like a dwarf gourami in the blue color, but that's the only fish I can think of for now. Any ideas?
