Fish are showing red streaks and blotches under there scales. I dont think they are going to make it long term.
Uploading a few photos to somewhere like www.imageshack.com might help, so forum members can look at these things that are concerning you

Edit: In these early critical stages of a new tank, I'd advise you to only add another small amount of fish (less than the "volume" of your current Danios) once you have had two complete weeks of water readings being zero for both ammonia (which should be helped by the plants) and nitrIte (which will need to be processed into the less toxic nitrAte by bacteria, plants are not believed to use nitrite, but they will use some of the nitrAte).
If things work out ok with these four guys, I'd say get another three or four, as your next fish.
