My betta fish that I have had for about 4 years finally kicked the bucket, so I decided to go out and purchase a new tank with a light on top. I ended up getting a 2.5 gallon tank and decorated it with a spongebob theme! The tank is long and fits perfectly on the back of my dresser so that I can look at it while in bed. There are three light settings. Bright white, blue, and blue and white.
