This is my Betta, Tazz. I'm currently treating Tazz for a mild case of Fin Rot. I wasn't adding anything to his water (tap water filtered with Brita) and sometimes I was going 2 weeks between cleaning. I've started adding aquarium salt and Aquarisol to his water and I'm doing full water changes every 3-4 days. I've ordered Tetracycline and a Betta First Aid Kit from www.bettatalk.com. I keep Tazz in a really nice 3 gallon tank called a Picotope. It's not big enough for a filter, but it stays clean longer than a typical 1 gallon bowl (and I like him having a nice big space to enjoy). Tazz has a rock sculpture and 2 fake plants. I have a desk lamp with a dimmer set up behind his tank so I can regulate the water temperature. The Picotope comes with a small heat lamp, but I don't like how it looks. This is my first Betta, Clyde (RIP) in the Picotope.
