Ok ok I see it a nitrite test. With reading that low for ammonia and nitrites. You should have nitrate readings. What does that test look like. Now, remember you have to follow that test to the letter and shake the heck out of the bottles!
From what I can see of the color in those tubes. I would say your tank is cycled. It's better if you put the card behind the test tubes by the way.
Sounds ok. I'm not a huge barb fan but that's just me. Tiger barb have to be kept in a shoal of at least 5, If not they are terrorist's in a tank in my experience. This is a good site to to check your stock list with. www.aqadvisor.com
