I currently have a betta in a 5 gallon. When I move out I want to get another bigger tank 10-15 gallons (20 max). I'm looking for hardy fish, I would love yellow/gold fish. Its hard to decide, i like the look of tetras, platies and mollys but open to anything. 😊

Are you planning on keeping them with the betta or keeping your 5 gallon with betta and getting a separate 10-15 gallon?

Getting a separate tank for the other fish

Have you considered gold white cloud minnows? You could have a good sized school in a heavily planted 15 gallon along with a bunch of shrimp (if you like them) and not even have to bother with a heater.
