Michael, "Creepy" and "Ugly" named by my girlfriend lived a 20 Gallon Long Tank, I used a Aqueon Quit Flow 20 as a filter along with a small air pump with a air stone. I only had aquarium slate in the tank for décor and to give them hiding spots which were bought from a aquarium store and cleaned. I used "Prime" Water Conditioner to remove Ammonia, and to detox Nitrites and Nitrates, I also used "API" Tap Water Conditioner to Dechlorinate. I was doing 25% water changes about every 10 days.
