1. I have a 5 gallon tank for my betta. I fill it with Deer Park natural spring water. It's an unfiltered tank, so how often should I change the water?
2. I feed my betta 4 pellets three times a week on Monday, Wednesday, & Friday. The betta fasts over the weekend. Is this a good feeding schedule?
3. I will be going away on vacation for a little over 2 weeks in October. How often should I have someone come in an feed my betta?
4. The tank is unheated, but the temperature of the room is always between 74 and 78 degrees. Is that temperature range OK for bettas?
Answers to these 4 questions would be greatly appreciated. Thank you.
