I ran out and got a bigger (6.5 gallon) tank for the betta ( caught my eye) that I got yesterday. I had the betta in a 1-gallon tank for only one night. the tank is an Aqua Culture 6.5-Gal Semi-Hex Aquarium Kit with LED Lighting and Power Filter from Walmart. I picked up the gravel, a small heater, and the fake plants too.
