Okay, I have this feeling like I am going to get many different answers to this question, but here goes.
I recently got 2 female Bettas that I was hoping would live together. I have since discovered that 2 is the worst amount that you can have and that was correct because all they want to do is fight each other. So, I got a tank divider and I have them both housed in a 10 gallon tank.
I don't have a heater or a filter.... YET!
I plan on getting both very soon after being convinced that I need both.
So, my question involves water changes, as the subject line indicates. I just found Mr. Vampire's website and I noticed that on his site he recommends for a 10 gallon tank (with a filter) that you do a 25%-50% water change once a month
I keep cichlids and have kept other fish in the past and that sounds really extreme to me. My first thought is that by the time I do that once a month water change on the 10 gallon, the ammonia levels would have to be off the charts!
Now, I am not one to question an experienced breeder and all so maybe I just need some more clarification on this issue? Can 2 female Bettas with a filter really go a whole month without a water change and not suffer any adverse effects?
Until I get that filter, how often should I be changing the water?
