I have this tank.
http://www.petsmart.com/product/inde...AvailInUS%2FNo I've had it for 3-4 months, cycled, with a betta in it. The betta died about 1.5 weeks ago, and the tank has just been sitting with all of the water (not running the filter) since then. I actually got it from walmart, but it's the same thing basically. The white LED lights have gone out, so now I just have blue lights which makes it very hard to see a betta. I would like to put fish in it though... I don't know what killed the betta, and that is why I didn't get another one to replace it right away. The cycle is most probably dead now, so I would have to start all over. I have a 5 gallon with 1 male betta, and a 10 gallon with 3 males that I could use to jump start the cycle, but I wouldn't know the best way. I was thinking that if I didn't get another betta, that I would get glowfish, or some other colorful fish. How many would fit? Where would I start!?
