Nano Betta Tank

I know this forum is for saltwater, but i thought i put my freshwater nano tank on display. This is a Deep Blue Professional 2.2 gallon rimless tank. It has a DBP nano filter system ...its 16 GPH with a DBP Solar flare nano led black light. the tank has 2.5 pounds of premium black sand. It looks purple because of the black light. In the tank has a skull ornament. The fish are a red male dragon phase betta fish and one Endler fish. Hope you like it.
