Jasurf21: I completely disagree. When I take my betta out to clean his tank and put him in a little .5 gallon container I bought he hates it. I can see his personality change right off the bat, but when I put him back in the tank he is happy again. Bettas are tropical fish. I like to keep the water around 73 degrees. Room temp and water temp are not the same. The water is most likely two degrees colder. Petsmart sells a tank for about 50 bucks that is a 10 gallon with everything you need to get started. IMO for a new tank it is not a bad deal. Sure you have to get decorations but smaller 5 gallon tanks can be expensive too. Petco is where I bought my last betta because my LFS didnt have any at the time. He is an extremely healthy little delta tail male however the ones at my petsmart were not so great looking. I know that this may seem expensive but in the end you could also put a school of 6 neon tetras in there with the betta. That way they have stuff to do, in the end I am sure the betta would be happy, He may hide but only because he is shy until he gets used to you. But eventually they will come out and play and dance for you, I swear bubbles knows his name
every time I say it he swims to the front of the glass. or maybe he just sees me looking at the tank either way
its cute. Point of the story is if you want a happy healthy betta put him in a bigger tank. even a 5 gallon works if he has it all to himself. and make sure you have a heater. the aquarium I told you about early is sold with a heater.
sorry for edit fixed typo. it said i kept the betta in 3 degrees water
