Hi guys! I'm going to be stocking my 15 gallon soon, and I'm wondering what kind of fish to get. Er... how many, rather. I already know that I want some or one dwarf gouramis and at least three guppies. My aquarium is already set up and running, with decorations, gravel and a running filter. Even a pH tester and an ammonia tester. Everything is good, and I'm just wondering if I'm being realistic with the wants of my tank. It is also a column, so I'm wondering if these fish might not be good in a tall tank. Thanks in advance!
