He is so pretty! I know it's a girl's name, but I don't think he minds too much! Besides, he looks just like my first one! I hope I have become a better betta keeper since then. I have read so much info on caring for him that I'm not sure what is right. I have him in a 2.5 gallon with a filter and a heater. Even though I have the filter, I know I will have to do a water change. Could someone please explain the steps I need to do a proper water change? Like how often, do I leave him in the tank during, do I treat the replacement water first then add it to the existing tank water? I have read so many different things that I'm now not sure what to do! Thanks for any suggestions.
