Hi! I am a complete novice about betta fish. Thank you for this blog site - it has answered alot of questions for me. We "won" our betta fish, Bluey, about a year and a half ago at a kid's birthday party. We bought him a betta fish bowl kit - which is about a one-gallon plastic bowl with a small green plastic plant in it. He seems healthy, he swims around, he eats his food as soon as I sprinkle it in, and he is a beautiful deep blue color. He hides inside his little plant sometimes. I am wondering if I should upgrade to a new 5 or 6 gallon tank with filter and heater - I am afraid the change will kill him. He has lived this long in his little bowl in our kitchen. what should i do? Thanks!

 

Do it! It won't kill him at all. So long as you do everything right. Your betta would love a bigger home. And having a filter always makes it easier.
