I love the smaller tanks.  My favorite right now is a 5g bow front tank.  I can pick this one up and move it to the sink if need be to take care of it.  This tank has been set up since Feb. with some plants in it. 

 Although the plants have stayed green and pretty I felt it might do better if I did it with soil. 

So I got out my "Ecology of the Planted Aquarium" book by Diana Walstad reread it and then redid my tank. (Even if you keep a high tech planted tank I recommend reading this book it has great info on how and why planted tanks work so well for filtering your water)

  This is a day one picture.  Ill update this later as the tank grows out.  Also I have some more plants on order that should arrive next week sometime.  Some fast growing floating plants.

This tank houses 6 white cloud mountian minnows and one beta.  I have a 10g in the works that I plan to house ghost shrimp and a beta.
