I'm setting up my new betta home, and I wanted to double check that I have everything I need.
-a 2.5 gallon tank
-a small filter (a filter recommended on this website)
-a small undergravel heater
-poland spring water (with water conditioner)
-a "cave" for fishie to hide in
-a little plant
-a small thermometer
After doing the research, I think this set up would require a water change twice a week. I'm still a little confused about the pH/water testing. How often should this be done? This set up is for one male betta.
