Hi! I've had my betta Finnick, Fin for short (still not sure wht tail he is :shock for about a year and a half. He's been in the same environment, same 1 plant, same coloured gravel, same rocks, etc. ever since I put him in his 2 gallon bowl. I know bettas like change, but would it be to much to change his plant maybe add another, change the gravel, add a cave, and get rid of all the rocks? Or in other words completely changing his environment. So do you think it's to much?
