I have a .5 gallon tank for one crowntail Betta fish. I use dechlorinated tap water. There's a plastic plant, a live plant bulb waiting to sprout, a small dragon statue from Petco, gravel, a small aquatic snail shell and a small plastic Poliwag I found while cleaning my closet the other day. I feed my Betta freezedried bloodworms once a day, and there's no filter. The problem is that the water gets cloudy, and an oily film develops on the surface of the water. I've been told I need a filter, but I can't find a .5 gallon filter. I was wondering if you guys could help, since I'm not sure if something like a 1 or 2 gallon filter would be too strong...
