We got a female betta fish for my son about a year and a half ago. She is in a 3 gallon tank with filter. After reading from this sub I am thinking I need to get her a larger tank with some real plants.

My question is her color. She has gotten much darker which I thought was due to aging. But could there be something wrong? She is still active but enjoys hiding in her little houses I change when I change her water. I have only bought the preconditioned water on the large jugs because it seems to be easiest. But it does cost more.

Any suggestions would be appreciated. She is loved and is 1.5 years old. Just want to give her the healthiest life possible. Please and thank you. I’ve posted just getting her over a year ago to today.
